For Canadians I found certified fuel rated hose 3/32" (2.38mm) ID x 3/16"OD, 100psi (690kPl, 9bar)) at Home Debit, . It's in the plumbing department with the white nylon hose. It's easier to bend then the nylon hose and wont kink, but the material is far less compressible than the cheap soft hose that come with most diesel heaters. Made by Canada Tubing Products, part # SUFD10, it was less than $10 for 10' (3m). I tried heating the line to see if it would slip on, it won't, so you will still have to get attach the same way as in John's excellent videos
Hi Mark, we can't get that here, but I can find something similar on Amazon - www.amazon.ca/Platic-Poulan-Craftsman-Weedeater-Mower/dp/B0CZDRVGFS/ref=sr_1_2?dib=eyJ2IjoiMSJ9.p0ynkzovCTeoMaDVfjVs92vWBI7i6YPHCotAYP4y6yL5o3hEEYL5g1H8C7r90yepn7JgXPp8pleqRfPJEEDh7CwQz-Ntwx_gOLynfWjQ5Xwk0SLGVuOhOzUNp9z6MhgR8YEJGIIa1MC88fbrGFn1HmvufURiL53XTZEsWHyj2z0IzaYS7ZGFOKYGanDQbm1lyxknhyUNfy20-JOvhx5sg6x-pwLQCgWsX-9DwlkQJWbgBG3Kogm2HoKXrQh7QgK9dXaLCNwOhyS69LQSxusTgQ6-ePBnmBV4BSQkEby3q3U.GBxsemIddPMRlQfvnPKHzBFhinINBsXwl8sMRiznngk&dib_tag=se&hvadid=605318916377&hvdev=c&hvlocphy=9198475&hvnetw=g&hvqmt=e&hvrand=3299220485140925718&hvtargid=kwd-325786320843&hydadcr=10441_13533794&keywords=3%2F32+fuel+line&qid=1724611236&sr=8-2 Would that work?
This is 1 of the most knowable diesel heater RUclipsrs out there! 4 years ago when I bought my first diesel heater and had any troubles, John is the best most experienced diesel heater technician out there. Now YT is full of diesel heater videos and I bet most of them got their info from John.
I have tried it both ways and the supplied soft large bore fuel line did work, however the small hard line as described by John did work MUCH better! It's little nuggets of knowledge like this that should make John's entire series on these heaters mandatory for anyone purchasing one of these heaters. You owe it to yourself to watch this incredibly well researched series. Tons of knowledge in each episode. Thank you John for all of the hard work that these videos must have entailed!
Hi 74 Willy, First thanks for your kind comments. Yes, the soft large bore fuel hose will work (for a while) If the length from pump to heater is short it will work for longer. The issue is this is not like a normal internal combustion motor with a carburettor, more like a fuel injected motor where the fuel is injected into the engine. In this case into a glow plug atomisation screen to start the heater and then into a big burner atomisation screen to run the heater. (See how far you would get using soft fuel hose to car engine injectors) The diesel must be squirted into these screens for atomisation. Soft fuel hose absorbs the fuel pulses, which causes lack of atomisation, which then causes carbon formation, which causes restriction to fuel passage, which causes more carbon, which causes more restrictions, causing more carbon etc. If the fuel delivery is short and you were only supplied with cheap transparent plastic fuel hose and can't source hard nylon fuel hose, at the very least buy some quality automotive fuel hose. Cheers. JMcK
Wow. John clearly demonstrates such a comprehensive understanding of these systems both in theory and in practice, evidently from many years of experience and critical thought. Whilst there are many videos simply documenting an amateur install, these videos establish a knowledge of the core principals. It is very enabling, educational and such a great opportunity to learn more deeply about ubiquitous systems and reduce failure in these types of components.
Bruce Argyle Hi Bruce, there are a number of online sellers. Search hard nylon fuel hose for Eberspacher diesel heater. I don't like to list suppliers in the description as sellers come and go. The last supplier I bought hose from is no longer there. I just did a quick search to get you started. See below. www.ebay.com.au/itm/Diesel-Heater-Nylon-Fuel-Line-OD5mm-ID1-5mm-7m-/333785075903?_trksid=p2349624.m46890.l49292 Cheers. JMcK
Bruce Argyle Hi Bruce, The ID is not so critical, 1.5 mm to 3 mm ok. Probably 2 mm ID would be ideal. It is “hard” part that matters. The pump puts out pulses (squirts) of fuel, and a soft fuel hose on the delivery side of the pump absorbs these pulses making the fuel delivery to the heater less efficient. The outer diameter does not really matter, but thicker (stiffer) is preferable to thinner. Cheers. JMcK
I can’t tell you how much I appreciate you taking the time to share these videos! You’re the only dude out there with proper videos on these Chinese heaters. Thank you!
Thanks for all the videos. At first I thought it was an overkill to do it so thoroughly, but I've watched most of them and they were really interesting and eye opening to the obvious truths :) Definitely cleared all the doubts I had before instaling my unit. Best regards from Poland!
We are fortunate to have someone as talented as you providing this priceless information on the intricate details of what looks like a purely simple system. I can’t imagine the amount of time you must have spent to produce these videos 🤔 Certainly the data shipped with these units is inadequate, hard to interpret at best and flat dangerous at worst. As a retired Cat diesel mechanic, I thought I knew all I needed to know for such a simple device, and in fact, I had no issues with my shop workspace installation, but am thinking of your attention to detail on butting the small id rigid tubing within the soft hose connections to prevent an accumulator effect, cavitation etc. Although I was careful, I fell short of verifying all those points and think I will go over my fuel delivery system to make sure it is in optimum shape. Even thinking of doing a micro and I do mean “micro” bevel at the hard line cuts. As I said, my machine is performing very well, but with such tiny flow rates everything must be very precise for a clean efficient trouble free burn. I have my unit mounted high in my shop and the fuel tank is low as is the filter and pump, but I’m asking the dosing pump to lift the fuel straight up seven feet or a little over two meters, and while it’s working fine now ; I should probably change that for the long haul. Thanks so much for the great information! “💡”Have you ever thought of contracting with these Chinese manufacturers to write a proper discernible installation/troubleshooting manual? Cheers 🍻👍
Hi Siskyiou, thank you for the feedback. I think bevels are not necessary, but a 2 m push for the pump is right on the limit. If your heater is working well with no smoking I would leave it be. I would love feedback on how the pump performs at that hight. J
Hi Mr Si. Reading this again, I tend to think your proactive thoughts may prevent issues with your heater in the future particularly as you are asking a lot of the little dosing pump. Re the manuals, the Chinese have copied much of the genuine Eberspacher Manual, from German to Chinese and then appear to translate from Chinese to English. The English version of the Eberspacher D4 manual is well worth reading.
Hi John McK 47, I’ve verified the the plastic fuel line is butted at the tank, filter, pump and the input at the main unit but did not take the time to micro bevel the tubing as the way I cut it didn’t smash the tubing. I was however inaccurate in my fuel lift estimation as it is only 5.5’ a bit under 2 meters and the pump is gravity fed at fuel tank levels above 1/3. I’ve got 8 hours of run time and everything is looking good. Thanks for the information on the OEM manual, I will be looking into that🤓 Oh, and I sprung for the “8 kw unit” because of the type of space I’m heating and of coarse now know that it’s really a 5 kw. For the extra $40 dollars I got a fancy fake carbon fiber paint job ha ha🙃 Live and learn, but I’m happy with its performance just the same.
You are an excellent teacher! You teach the "how" and the "why" which empowers your viewers to figure out the best way to install their heaters for their particular situation. Cheers!
I never considered the hydrostatic pressure aspect of the fuel delivery line but makes a lot of sense now why you'd want to use the 'hard line'. My heater is coming in Saturday for my cargo trailer conversion and after watching your videos I'm confident in installing it correctly! Thanks John!
Thank you soo much for this video I was experiencing the E 10 error on my Chinese Diesel heater, which was installed with the supplied 5m inner pipe. Changed to the Webasto nylon pipe 5mm outer and 2mm inner which I got off Ebay. After priming It started first time. You're a star for putting this video together and sharing your obvious immense knowledge.
I am a lady (so ignorant as far as how things work mechanically) and have been pulling my hair out trying to instal the heater in my caravan with badly translated instructions and worse illustrations. I had thought the supplier had sent the wrong fuel line - the hard type that did not fit the fittings, so I went out and bought the bigger soft fuel line. Have attached it all but still have to do the exhaust etc. Thank heavens for this very explicit video. I will now have to replace all of the fuel line with the original supplied, especially now I know how to join to the fitting. I have watched quite a few videos trying to get some insight as to installation and none go into enough detail. Thank you so much.
Hi Carol, Thank you for the feedback. It is generally ok to have the soft fuel line on the intake side of the pump, provided it is of a short distance. But you really need the narrow bore hard nylon on the outlet side of the pump. Good luck with your install. When set up right, these heaters give wonderful dry heat for those cold winter days. JMcK
One of the most informative, comprehensive and demonstrative RUclips vids I’ve ever seen. Thank you John you are an Aussie gem. This to me is what RUclips is all about. Education from people who (obviously) know what they’re talking about. John if I see you in the road I owe you a beer mate. Cheers. Pete
Hi Peter, I received an email notification from RUclips where you were having trouble priming the fuel line, but when I went to the site your post had disappeared. Did you remove it or has it gone into the cloud somewhere. If you did not remove it can you please post it again, or email me at johnmck47@outlook.com. JMcK
Thank you John !! I am so very happy with your videos, learned so much! One hint for users who are thinking (like me) about installing the so called "silent pump" by james browning-smith: This pump is a better "sucker" than the standard issue noisy model, so that the pump should be mounted near the heater - the setup is: fuel tank - filter - longer part of the fuel line - pump - short fuel line - diesel heater.
Great video mate, thanks for the advice. I have just bought a heater and was going to use a better quality rubber fuel line instead of the nylon. You saved me some dramas!!
Hi Andy, You can use quality fuel hose from tank to pump to eliminate all the joiners. Remember this distance needs to be short. You can also use quality fuel hose after the pump for short runs, 1m to 2m. Anything over that you really need to use the small bore hard nylon tubing. Good luck. JMcK
Thanks for that😊 I plumbed mine up last night with 3/16 fuel line it's only about 1m from pump to heater goes around a few corners of the caravan chassis but I put my pump facing downhill? That's what everyone else says? My tanks bottom is on the same level as heater (on van floor) but pump and filter are under van . Total hose used was 1.9m but I have about .5 to filter then .3 to pump. Do you think I should replace from pump to heater with the nylon supplied and change pump angle? Thanks Darren
Good explanation. I really like guys like you. When I was a kid, there where guys like you everywhere (no offense), guess I took it for granted. But now? You're a treasure and getting rarer by the day. Glad you're making videos!
Thanks for all these helpful videos! I've just purchased my first heater and have been installing it into a portable box for camping with our rooftop tent. I think I will have done everything twice by the time I'm done with this build because I didn't take the time to watch all your videos before I got started. Thankfully, I haven't been in a rush so I can fix the way I ran the fuel piping before running the system. In case anyone is interested, I just bought a Vevor 2kW unit (Dec 2021) and it came with the smaller gauge nylon (preferred) tubing and some rubber hose for the connections.
@@johnmck1147 Hi. John . i´m from Germany and are Diesel is as clean as in the rest of the world ;-) but i think the reason why the orignal German diesel heater only have that tiny filter installed is becouse they are mainly made for cars and the diesel comes in taht case from the car tank .. in that case the car has a filter systen wich is allready installed by the car manufactor. and thats why there seems no need for a nother big filter system Kind regards Willi
I would have never thought this inexpensive heater would be so well engineered needing so much attention during the parts selection and subsequent installation. Your video series on this device is saving me money and saving money is my priority in life. Hand salute!!
THANK YOU SIR ! For your hard work and knowledge of diesel heaters. I am still watching your series. I feel you are the best provider of this needed information.
I finally pulled the trigger and bought a diesel heater. I received my heater today and was annoyed with the " wrong size hose" that was supplied. I started looking at larger bore hose, but decided to revisit your channel as I've been here before. After watching Part 11, I am now educated on the fuel delivery aspect and thankful for your help. Who would have thought 2mm's along with material could make such a difference. Thanks for the awesome information John.
Best advice for these heaters, hands down! I bought an hcalory heater here in the US and it had that very problem you described, with the wilder flexible tubing. It created a big air pocket. I switched it all out to the stiffer tubing. I wish I had seen this video before I did that just 2 days ago because I didn't make sure the The Tubing was pushed all the way in to the black rubber pieces, but I think that won't matter much because I have the clamps on pretty tight, fingers crossed. I did extend my exhaust pipe with 3/4" emt pipe to get exhaust further away from air intake. That was a big factor in my install.
I can't tell you how much I appreciate all of the wisdom in your videos. I would have just dropped one in my van and made at least 3 mistakes and then bi!ch about the crappry heater. Thank you very much! Soo much info. Even just your side comments are so informative and insightful. Thanks for all the hard work and time making these videos. I would pay for all this info. Maybe it could be a book on Amazon?
Thanks John as a retired brit trucker living in the USA and boondocking, i had trouble with a worn pump although not more than a couple of weeks use,i started from the fuel tank checked the flow downhill and flat,and checked joints ends of pipes,got a puff of smoke once,but as soon as i put a new pump on, no more problems !!! I guess now i know for sure the fuel flow is good. Thank you for your videos a great source of info. I still had a piece of the fue line they used in the 80's in my toolbox black plastic 2mm inside but twice as thick as what you get now.
@@johnmck1147 yes,i got larger model filter a couple of inches from the fuel supply.great when it works correctly,using it right now (26f outside). I love my night heater Thanks J
@@johnmck1147 checked my fuel filter,after a couple of days use,very fine (sand) grit in there,most likely what tore up my previous pump. Thanks again John
Hey John "Great Vid" I've just bought a Diesel Heater and realised the vynil hose needed an upgrade, my heater now runs very nicely with 2mm nylon hose. I lived in Vic between 04 to 08 and listerning to youre Magpies made me smile, tho I don't miss the Butcher bird's calling at 5am.. take it easy.....
Best video explaining the details and subtleties of fuel delivery and ignition for diesel heaters and the importance of the component parts working properly together. Well done !!
I will be fitting a diesel air heater to the Campervan I'm fitting out . John , thank you very much for the information that you are sharing . You're a wealth of knowledge !
John, Thank you so much for providing these great video's on the diesel heaters. I feel so much more confident that I will be able to set my heater up so I am able to use it ice fishing here in Manitoba, Canada. You have done a great job on these video's my son and I thank you for your efforts.
Thank you! I had my heater fitted for me and have had fuel problems since - he used a flexible hose! I will swap it today. Appreciate you taking time to explain this
Thanks so much, you've solved all my problems. I'm on my third pump after returning the first two because they were creating air bubbles! Just installed nylon line and working well so far :)
GREAT info. The manual in my heater box did NOT say anything about the fuel line. Thank you very much for explaining the whole process so clearly. I've been trying to get this thing running for a few days now!!! So tmrw I should get some heat out of it!!! Tks again.
Mate, thanks. This is so clear and easy to understand. Unlike the instructions in the box, which don't say much anyway and what they do say is not really in Engrish. Could have guessed my way through most of it, but probably would have spend the next couple of months working out what I did wrong! Tidy.
i just got a heater and installed it in my vw transporter, now watching your videos for tips and preventative measures, great that youve taken so much time and made the effort, all the best from cold and rainy uk
So very very helpful I was stumped when I saw the small hose supplied and thought I’d be duped But you very succinctly explained it all in an easy straight forward way. Saved the day Cheers
Great insight on the fuel delivery and dosing into the atomizer. Wow, your explanation is so in depth and detailed with real lab work. I absolutely appreciate you sir.
Thank you very much John for taking the time to help us. Your videos are invaluable for those like me they face the installation of these Chinese heater. Most of these are delivered without instruction or unreadable translation from chinese to english. Forever your debtor.
Thanks for a clear wexplanation of why it's helpful to use the right size fuel line. A little less than the size of a wodden match for I.D. (bore) is helpful info,
@@tubbekans It is not so much the bore size, but the fact that the delivery fuel line from the pump to heater is non flexible, particularly if the hose run is more than a foot or so. Flexible line absorbs the fuel pump pulses and hence there is not enough force to force the fuel through the atomisation screens in the burner. JMcK
Thanks John you answered every question I needed to know, I thought I had ordered the wrong fuel line, because it was to thin after watching your video I was jumping for joy many many thanks, big thumbs up.
I was thinking to install heater this weekend, but after I've watched your video, nylon pipe has been ordered and I'll fit this when new fuel line arrives. Many thanks
Thank You for sharing your knowledge, you are a great teacher. I was thinking you must be an engineer. I see this is part 11, i need to looks at your other video`s to get up to speed. The problems I see with these heaters is operator error. I just received the Vevor Heater a week ago. been doing a lot of reading on setting them up, and saw a couple video`s on replacing the vinyl fuel line to the nylon type. just received my kit in the mail today. 12/21/24. There is also listed on E-Bay a steel fuel line that fits into a plastic 5 Gallon fuel container Cap/Lid. This will extend the run time, and possibly lessen the fuel spillage trying to pour into the small tank. This heater is going to heat my 18 X 30Ft shop, gets pretty cold here in northern Nevada in the winter. Great Video, Thank You
@@charlieLund-v4r Pleased you found videos helpful.. If heater is outside shop in freezing weather, suggest you try a 90/10 kerro to diesel mix. Less fuel gelling problems. JMcK
John, this is the only video of yours I've watched (yet!), But it is awesome. Thank you so much for taking the time to do this! If it wasn't for you making such comprehensive videos, many of us users would struggle to get these things working properly. Thank you!
Great high quality video from distance to close up fine detail focus. I consider myself lucky in finding such quality detailing of proper installation as well as to why the work has to be done properly and as to the failures that happen when there is not enough information from the factory! THANKS!!!
Yes, you can get fuel leakage leading to flooding of heater and lots of smoke on start up. Just add a fuel shut off tap in the fuel line before fuel filter and turn this off if not using the heater for a few days. JMcK
Some great engineering principles explained here. I bought a Vevor® "square brick" heater box but it didn't last long. Turns out the hard tube inside had a few factory installed coils so the bubbles were collecting up top and the atomizer screen was all carboned up. A thorough cleanout and rerouting the tubes fixed it good! So if you buy any of the box units take the cover off and inspect the tubing!
Fantastic series of videos, thank you for taking the considerable time it takes to produce them. So much bullshit and absolute guesses are sprouted out there by the uninformed. It's an absolute pleasure to watch someone who obviously knows his stuff about these units.
Hi John, Just coming across your videos having just installed a 5Kw unit into my caravan ready for the winter. Very informative regarding the fuel hose and delivery system, since I have only once since installation a week ago had a successful run of the heater. Suffice to say, mine came with the poor vinyl large bore fuel line, which I see now I need to replace from the pump. (luckily I have plenty of the 4mm hard bore hose in my workshop). Another issue is that in the caravan, I am very limited in installation location of heater and fuel tank, such that without putting the pump outside / under the van on the chassis, it's near impossible to get a steady incline up to the feed point of the heater. What happens currently is the heater will not properly ignite, makes a very impressive smoke generator with clouds of white diesel vapour!! It's good to see from your video now how I can hopefully resolve my problems just changing the feedline! Thanks for the great info in your videos. ;)
I’ve just installed my new heater and it wouldn’t run properly. Ran for a few minutes then went off. It came with soft green fuel line. All that happened was very little heat output lots of white smoke and diesel dripping from the exhaust muffler and E10 error message. After priming at least 10 times and trying again I watched your very informative video and have ordered the proper hard small bore nylon hose. Hopefully this will fix my issue. Many thanks for the great video…….Very helpful
Hi John, great run down. I was about to go and buy some large diameter fuel line as I couldn't work out how the small stuff was supposed to fit. You've just saved me money and no doubt some frustrations. Thanks.
Hi Andrew, you can run standard fuel hose from tank to pump on the suction side, but should only use hard nylon small bore tube on the delivery side of the pump. JMcK
Hi John, I sure do appreciate your knowledge and your willingness to share with terrific videos. I have heard through RUclips that winter diesel is not good to use in the heaters. Winter diesel is sold here in Canada during the winter. Regular diesel will gel and can not be used in cold weather. I guess the problem is finding Regular diesel here.
@@green-zone36 Hi G, Thankfully in Aus, we do not have that bitter weather you get in Canada. I suggest you try running kerosene in the heater in winter. If you have heating kerro with a bit of sulphur in it you can run it neat. If very pure lighting kerro, and you use the heater a lot, perhaps adding 10% diesel, for pump lubrication may be something to do. Please let me know how it goes. JMcK
I have a Hcalory heater that has never fired up, I just get an E 10 error code as well as fuel dripping out of the exhaust - as well as a duff glow plug I suspect the fuel pipe has issues, it is a combined tank and heater unit and there is a fantastic bubble collector where the tube drops to the heater from the pump. I found your content very enlightening as to why we need to use hard line of the correct diameter. i will order both and try again. when you mentioned tubes running up hill i initially questioned that but upon explanation it makes perfect sense - bubbles travel up hill so no collection points on route. The manufacturers should make these things the other way round with the tank on the bottom so that its all up hill. Oh dear i'm waffling - stay safe
How did I not think of that by my self... larger diameter, more volume to pull... larger volume, bubbles joyn... THANK YOU, not just for here but also elsewhee, moment of AHAAAAAA !!!!
John I genuinely enjoyed your video. All the detail along with the props you used and even going as far as setting up the hose display was excellent. Thank you for putting all the time that you did in making this video. I am looking forward to seeing some of the other videos you've uploaded. Best wishes!
Brilliant. You can't beat old school who know their onions! I think you've saved me a lot of tears showing the shortcomings of the Chinese copy, which I'll be fitting shortly to the brother in laws' motorhome. I was going to tap into the fuel tank auxiliary if it has one and use copper brake pipe as I have plenty and the flaring tool, nuts and connectors but your suggestion of 2mm nylon might be a better way to go. Many thanks.
Thanks for rigging up the models, mate. Really gives a solid understanding of what's going on in these things. Until i watched this vid, i knew the diesel went in the hole and made heat come out. I've got a much better awareness of what's going on in my heater now. Thanks!
Installing mine as I watch, keep coming in for a re-cap from my notes I took from these videos a couple of month ago. Brilliant information - thanks again John.
@@johnmck1147 I have aspergers and need to know things are done to the absolute the best they can be..... No short cuts, no guessing or making do, solid factual scientific and practically tested methods where if followid..... Will get the best results. You videos give me the best platform to accomplish this. Wonderful.
Hi John, thanks for your great videos. I have just installed a 8 kw Chinese heater in a workshop and it works great. My heater came with a remote control and a small online fuel filter which is a lot better than the tiny filters which comes with the D2 Airtronic. It is a good idea to run the heaters at a high setting regularly to keep the combustion chamber clean. I think our diesel in Western Australia is pretty low quality as I travelled over east for several months, running the heater every day for about 8 hours with no problems and clean combustion, however, once back home it only took about 2 weeks to soot up the combustion chamber. Adding some kero and running the heater hot does cleans the soot a bit but usually I have to replace the screen in the ignition changer. I like your removal tool! Another problem I have encountered is a dust build up on the flame/ heat sensor mounted on the combustion chamber which can cause an error code. I found that the shortest length of the exhaust pipe possible will give longer periods between services, our diesel again. I have an Edith Diagnostics adapter for my Espar D2 heaters to work the error codes but have not had to use it much as I can usually figure out what causes the faults. Thanks again for you information. They are great space heaters,
Hi Peter, thank you for your detailed feedback. I agree with you about the variance of diesel quality and the need to keep the exhaust short or go larger. You also need to keep the combustion air intake short, or go larger. Glad you like my screen removal tool, but have you managed to source the very rare screen insertion tool? Cheers, JMcK
Truly an awesome video and demonstration. On paper, I don’t think there should be a problem with lifting fuel through a larger diameter line. The vacuum pressure at the top of a column would only depend on height not diameter. The pump would only be lifting the column of fuel within the cross-section of the pump inlet, not the entire volume of the hose. That being said, I’m taking your word for it!
Hey thank you sir for showing this effect of the soft tube compared to the hard tube. I'm experiencing leaks in my fuel line at the filter and at the pump. I'm considering replacing the soft tube that came with my heater with the hard fuel line kit I ordered
Nice information and explained very well. I will put this information into practice. You need to write the manual for these heaters as the installation instructions that come with them are hopeless. Well done.
Fitted 2 in my yacht, carboned up one on second day, watched your vid and now know I've been very naughty. I've learned much from you good sir, I will go forth repair and rectify my badness! Ta very much.
His advice and requirements are absolutely correct. Go to the eberspacher website and follow their install specs if you bought a Chinese diesel heater and save yourself a lot of time and aggravation
I havent watched it all yet.. but i put the fitting or a hole in the cap (dont drill out the bottom) with a length of smallest diameter hose (the hard nylone works perfectly) going to the near bottom of the tank. Mount it higher than the heater and ..presto.. the siphon effect keeps the pump primed.
This is a brilliant video, I'm currently installing mine in my boat and I was debating using automotive braided fuel line. As I thought the hard nylon line would be sceptical to cracking in cold weather.

For Canadians I found certified fuel rated hose 3/32" (2.38mm) ID x 3/16"OD, 100psi (690kPl, 9bar)) at Home Debit, . It's in the plumbing department with the white nylon hose. It's easier to bend then the nylon hose and wont kink, but the material is far less compressible than the cheap soft hose that come with most diesel heaters. Made by Canada Tubing Products, part # SUFD10, it was less than $10 for 10' (3m). I tried heating the line to see if it would slip on, it won't, so you will still have to get attach the same way as in John's excellent videos

This is 1 of the most knowable diesel heater RUclipsrs out there! 4 years ago when I bought my first diesel heater and had any troubles, John is the best most experienced diesel heater technician out there. Now YT is full of diesel heater videos and I bet most of them got their info from John.

Thank you for your kind words. Pleased you found these old videos helpful. JMcK
I have tried it both ways and the supplied soft large bore fuel line did work, however the small hard line as described by John did work MUCH better!
It's little nuggets of knowledge like this that should make John's entire series on these heaters mandatory for anyone purchasing one of these heaters. You owe it to yourself to watch this incredibly well researched series. Tons of knowledge in each episode.
Thank you John for all of the hard work that these videos must have entailed!
Hi 74 Willy,
First thanks for your kind comments.
Yes, the soft large bore fuel hose will work (for a while)
If the length from pump to heater is short it will work for longer.
The issue is this is not like a normal internal combustion motor with a carburettor, more like a fuel injected motor where the fuel is injected into the engine. In this case into a glow plug atomisation screen to start the heater and then into a big burner atomisation screen to run the heater. (See how far you would get using soft fuel hose to car engine injectors)
The diesel must be squirted into these screens for atomisation. Soft fuel hose absorbs the fuel pulses, which causes lack of atomisation, which then causes carbon formation, which causes restriction to fuel passage, which causes more carbon, which causes more restrictions, causing more carbon etc.
If the fuel delivery is short and you were only supplied with cheap transparent plastic fuel hose and can't source hard nylon fuel hose, at the very least buy some quality automotive fuel hose.
Cheers. JMcK
Wow. John clearly demonstrates such a comprehensive understanding of these systems both in theory and in practice, evidently from many years of experience and critical thought. Whilst there are many videos simply documenting an amateur install, these videos establish a knowledge of the core principals. It is very enabling, educational and such a great opportunity to learn more deeply about ubiquitous systems and reduce failure in these types of components.
Thanks for the positive feedback Tim
Hands down the best informational video for these heaters on RUclips.
Thank you . JMcK
Thanks. Lots of useful information, no unnecessary music, "hey what's up" or other bolleaux. Great video
Your welcome Jonathan. JMcK
@@johnmck1147 Hi John, Where can you purchase the nylon small internal diameter fuel line. Regards Bruce
Bruce Argyle
Hi Bruce, there are a number of online sellers.
Search hard nylon fuel hose for Eberspacher diesel heater.
I don't like to list suppliers in the description as sellers come and go. The last supplier I bought hose from is no longer there.
I just did a quick search to get you started. See below.
www.ebay.com.au/itm/Diesel-Heater-Nylon-Fuel-Line-OD5mm-ID1-5mm-7m-/333785075903?_trksid=p2349624.m46890.l49292
Cheers. JMcK
@@johnmck1147
Thanks John, didn’t seem to find a lot will retry. So what is the ideal inside and outside diameters.
Bruce Argyle
Hi Bruce,
The ID is not so critical, 1.5 mm to 3 mm ok.
Probably 2 mm ID would be ideal.
It is “hard” part that matters. The pump puts out pulses (squirts) of fuel, and a soft fuel hose on the delivery side of the pump absorbs these pulses making the fuel delivery to the heater less efficient. The outer diameter does not really matter, but thicker (stiffer) is preferable to thinner.
Cheers. JMcK
I can’t tell you how much I appreciate you taking the time to share these videos! You’re the only dude out there with proper videos on these Chinese heaters.
Thank you!
Thanks for the positive feedback Than. JMcK
John , thanks for the information.
Question , can i place my diesel tank on the roofrack of my van ?
To much pressure ?
Thanks for all the videos. At first I thought it was an overkill to do it so thoroughly, but I've watched most of them and they were really interesting and eye opening to the obvious truths :) Definitely cleared all the doubts I had before instaling my unit. Best regards from Poland!
Thank you for the feedback. JMcK
We are fortunate to have someone as talented as you providing this priceless information on the intricate details of what looks like a purely simple system. I can’t imagine the amount of time you must have spent to produce these videos 🤔 Certainly the data shipped with these units is inadequate, hard to interpret at best and flat dangerous at worst. As a retired Cat diesel mechanic, I thought I knew all I needed to know for such a simple device, and in fact, I had no issues with my shop workspace installation, but am thinking of your attention to detail on butting the small id rigid tubing within the soft hose connections to prevent an accumulator effect, cavitation etc. Although I was careful, I fell short of verifying all those points and think I will go over my fuel delivery system to make sure it is in optimum shape. Even thinking of doing a micro and I do mean “micro” bevel at the hard line cuts. As I said, my machine is performing very well, but with such tiny flow rates everything must be very precise for a clean efficient trouble free burn. I have my unit mounted high in my shop and the fuel tank is low as is the filter and pump, but I’m asking the dosing pump to lift the fuel straight up seven feet or a little over two meters, and while it’s working fine now ; I should probably change that for the long haul. Thanks so much for the great information! “💡”Have you ever thought of contracting with these Chinese manufacturers to write a proper discernible installation/troubleshooting manual? Cheers 🍻👍
Hi Siskyiou, thank you for the feedback. I think bevels are not necessary, but a 2 m push for the pump is right on the limit. If your heater is working well with no smoking I would leave it be. I would love feedback on how the pump performs at that hight. J
Hi Mr Si. Reading this again, I tend to think your proactive thoughts may prevent issues with your heater in the future particularly as you are asking a lot of the little dosing pump.
Re the manuals, the Chinese have copied much of the genuine Eberspacher Manual, from German to Chinese and then appear to translate from Chinese to English. The English version of the Eberspacher D4 manual is well worth reading.
Hi John McK 47, I’ve verified the the plastic fuel line is butted at the tank, filter, pump and the input at the main unit but did not take the time to micro bevel the tubing as the way I cut it didn’t smash the tubing. I was however inaccurate in my fuel lift estimation as it is only 5.5’ a bit under 2 meters and the pump is gravity fed at fuel tank levels above 1/3. I’ve got 8 hours of run time and everything is looking good. Thanks for the information on the OEM manual, I will be looking into that🤓 Oh, and I sprung for the “8 kw unit” because of the type of space I’m heating and of coarse now know that it’s really a 5 kw. For the extra $40 dollars I got a fancy fake carbon fiber paint job ha ha🙃 Live and learn, but I’m happy with its performance just the same.
Siskiyou Woodsmann, Sounds good. The height is a bonus as well. Enjoy the dry heat. J
You're a bloody LEGEND! :)

I never considered the hydrostatic pressure aspect of the fuel delivery line but makes a lot of sense now why you'd want to use the 'hard line'. My heater is coming in Saturday for my cargo trailer conversion and after watching your videos I'm confident in installing it correctly! Thanks John!
Thank you soo much for this video I was experiencing the E 10 error on my Chinese Diesel heater, which was installed with the supplied 5m inner pipe. Changed to the Webasto nylon pipe 5mm outer and 2mm inner which I got off Ebay. After priming It started first time. You're a star for putting this video together and sharing your obvious immense knowledge.
Thanks for the feedback TA. JMcK
I am a lady (so ignorant as far as how things work mechanically) and have been pulling my hair out trying to instal the heater in my caravan with badly translated instructions and worse illustrations. I had thought the supplier had sent the wrong fuel line - the hard type that did not fit the fittings, so I went out and bought the bigger soft fuel line. Have attached it all but still have to do the exhaust etc. Thank heavens for this very explicit video. I will now have to replace all of the fuel line with the original supplied, especially now I know how to join to the fitting. I have watched quite a few videos trying to get some insight as to installation and none go into enough detail. Thank you so much.
Hi Carol,
Thank you for the feedback. It is generally ok to have the soft fuel line on the intake side of the pump, provided it is of a short distance. But you really need the narrow bore hard nylon on the outlet side of the pump.
Good luck with your install. When set up right, these heaters give wonderful dry heat for those cold winter days. JMcK
One of the most informative, comprehensive and demonstrative RUclips vids I’ve ever seen. Thank you John you are an Aussie gem. This to me is what RUclips is all about. Education from people who (obviously) know what they’re talking about. John if I see you in the road I owe you a beer mate. Cheers. Pete
Hi Peter, I received an email notification from RUclips where you were having trouble priming the fuel line, but when I went to the site your post had disappeared. Did you remove it or has it gone into the cloud somewhere. If you did not remove it can you please post it again, or email me at johnmck47@outlook.com. JMcK
Woah, who would have thought bigger line wasn't better!
Thanks John!
John I avoided several mistakes watching your video! Thank you very much, you made my day.
Thank you John !! I am so very happy with your videos, learned so much! One hint for users who are thinking (like me) about installing the so called "silent pump" by james browning-smith: This pump is a better "sucker" than the standard issue noisy model, so that the pump should be mounted near the heater - the setup is: fuel tank - filter - longer part of the fuel line - pump - short fuel line - diesel heater.
Love how you did a full breakdown of the unit, it was really interesting and helpful. Most other video's don't go this in depth. Thanks!
Thanks for the positive feedback. JMcK
That was a great illustration rather than just talking and theory. Thanks for that.
Pleased you found it helpful Marty. JMcK
Great work! Thanks so much for these vids. Plain and simple to understand.
Thanks Robbie. JMcK
Just wanted to thank you for this excellent series. I actually installed an Eberspacher, but your wonderful videos were great 'enablers'. Many thanks.
Pleased you found them helpful Patrick. JMcK
Great video mate, thanks for the advice. I have just bought a heater and was going to use a better quality rubber fuel line instead of the nylon. You saved me some dramas!!
Hi Andy,
You can use quality fuel hose from tank to pump to eliminate all the joiners. Remember this distance needs to be short.
You can also use quality fuel hose after the pump for short runs, 1m to 2m. Anything over that you really need to use the small bore hard nylon tubing.
Good luck. JMcK
Thanks for that😊 I plumbed mine up last night with 3/16 fuel line it's only about 1m from pump to heater goes around a few corners of the caravan chassis but I put my pump facing downhill? That's what everyone else says? My tanks bottom is on the same level as heater (on van floor) but pump and filter are under van . Total hose used was 1.9m but I have about .5 to filter then .3 to pump. Do you think I should replace from pump to heater with the nylon supplied and change pump angle? Thanks Darren
Good explanation. I really like guys like you. When I was a kid, there where guys like you everywhere (no offense), guess I took it for granted. But now? You're a treasure and getting rarer by the day. Glad you're making videos!
Not sure what to say here……😳
Thanks for doing these videos!!!
Your welcome Patrick.
Thanks for all these helpful videos! I've just purchased my first heater and have been installing it into a portable box for camping with our rooftop tent. I think I will have done everything twice by the time I'm done with this build because I didn't take the time to watch all your videos before I got started. Thankfully, I haven't been in a rush so I can fix the way I ran the fuel piping before running the system. In case anyone is interested, I just bought a Vevor 2kW unit (Dec 2021) and it came with the smaller gauge nylon (preferred) tubing and some rubber hose for the connections.
Thanks for the feedback Kevin.
Happy New Year. JMcK
You're a bloody LEGEND! :)
Wow! Thanks Trewin.
@@johnmck1147 Hi. John . i´m from Germany and are Diesel is as clean as in the rest of the world ;-)
but i think the reason why the orignal German diesel heater only have that tiny filter installed is becouse they are mainly made for cars and the diesel comes in taht case from the car tank .. in that case the car has a filter systen wich is allready installed by the car manufactor. and thats why there seems no need for a nother big filter system
Kind regards Willi

Hi Willi, thank you for that info and feedback. Also my apologies for my wrong pronunciation of Eberspacher. JMcK
I would have never thought this inexpensive heater would be so well engineered needing so much attention during the parts selection and subsequent installation. Your video series on this device is saving me money and saving money is my priority in life. Hand salute!!
I am glad I was of some help to you. JMcK
THANK YOU SIR ! For your hard work and knowledge of diesel heaters. I am still watching your series. I feel you are the best provider of this needed information.

Your video's just saved my heater from being smashed with a hammer with frustration! Knowledge is key and thank you so much for sharing yours!
Oh dear Ian, you heater would not like that. I am glad I have been of some help. JMcK
I finally pulled the trigger and bought a diesel heater. I received my heater today and was annoyed with the " wrong size hose" that was supplied. I started looking at larger bore hose, but decided to revisit your channel as I've been here before. After watching Part 11, I am now educated on the fuel delivery aspect and thankful for your help. Who would have thought 2mm's along with material could make such a difference. Thanks for the awesome information John.
Thanks for the feedback Dforty. JMcK
Best advice for these heaters, hands down! I bought an hcalory heater here in the US and it had that very problem you described, with the wilder flexible tubing. It created a big air pocket. I switched it all out to the stiffer tubing. I wish I had seen this video before I did that just 2 days ago because I didn't make sure the The
Tubing was pushed all the way in to the black rubber pieces, but I think that won't matter much because I have the clamps on pretty tight, fingers crossed.
I did extend my exhaust pipe with 3/4" emt pipe to get exhaust further away from air intake. That was a big factor in my install.
I can't tell you how much I appreciate all of the wisdom in your videos. I would have just dropped one in my van and made at least 3 mistakes and then bi!ch about the crappry heater. Thank you very much! Soo much info. Even just your side comments are so informative and insightful. Thanks for all the hard work and time making these videos. I would pay for all this info. Maybe it could be a book on Amazon?
Wow Kevin, thanks for the positive feedback. JMcK
Thanks John as a retired brit trucker living in the USA and boondocking, i had trouble with a worn pump although not more than a couple of weeks use,i started from the fuel tank checked the flow downhill and flat,and checked joints ends of pipes,got a puff of smoke once,but as soon as i put a new pump on, no more problems !!!
I guess now i know for sure the fuel flow is good.
Thank you for your videos a great source of info.
I still had a piece of the fue line they used in the 80's in my toolbox black plastic 2mm inside but twice as thick as what you get now.
Hi Colin,,
Thanks for the info. Pleased things now ok.
I assume you have a good fuel filter in the line before the pump. JMcK
@@johnmck1147 yes,i got larger model filter a couple of inches from the fuel supply.great when it works correctly,using it right now (26f outside).

Mate, thanks.
This is so clear and easy to understand. Unlike the instructions in the box, which don't say much anyway and what they do say is not really in Engrish.
Could have guessed my way through most of it, but probably would have spend the next couple of months working out what I did wrong!

Thanks for a clear wexplanation of why it's helpful to use the right size fuel line. A little less than the size of a wodden match for I.D. (bore) is helpful info,
@@tubbekans
It is not so much the bore size, but the fact that the delivery fuel line from the pump to heater is non flexible, particularly if the hose run is more than a foot or so. Flexible line absorbs the fuel pump pulses and hence there is not enough force to force the fuel through the atomisation screens in the burner. JMcK
Thanks John you answered every question I needed to know, I thought I had ordered the wrong fuel line, because it was to thin after watching your video I was jumping for joy many many thanks, big thumbs up.

Good presentation John. Very good demonstration of the two different fuel lines effect on transmitting fuel pulses.
Thanks for the feedback Greolit
Thank You for sharing your knowledge, you are a great teacher. I was thinking you must be an engineer. I see this is part 11, i need to looks at your other video`s to get up to speed.
The problems I see with these heaters is operator error.
I just received the Vevor Heater a week ago. been doing a lot of reading on setting them up, and saw a couple video`s on replacing the vinyl fuel line to the nylon type. just received my kit in the mail today. 12/21/24.
There is also listed on E-Bay a steel fuel line that fits into a plastic 5 Gallon fuel container Cap/Lid.
This will extend the run time, and possibly lessen the fuel spillage trying to pour into the small tank.
This heater is going to heat my 18 X 30Ft shop, gets pretty cold here in northern Nevada in the winter.
Great Video, Thank You

Brilliant explanation, should be mandatory for anyone purchasing one of these heaters..thanks John
Pleased you found the videos helpful Martin. JMcK
Yes. The important thing is “hard” fuel hose. In commercial in an engine space you use thin copper fuel line. JMcK
Brilliant video , had problems with these heaters for years. Now I know why. Thank you!
Hi Hamish, pleased you found video helpful. JMcK
Yes, you can get fuel leakage leading to flooding of heater and lots of smoke on start up. Just add a fuel shut off tap in the fuel line before fuel filter and turn this off if not using the heater for a few days. JMcK
Some great engineering principles explained here. I bought a Vevor® "square brick" heater box but it didn't last long. Turns out the hard tube inside had a few factory installed coils so the bubbles were collecting up top and the atomizer screen was all carboned up. A thorough cleanout and rerouting the tubes fixed it good! So if you buy any of the box units take the cover off and inspect the tubing!
👍

Fantastic series of videos, thank you for taking the considerable time it takes to produce them.
So much bullshit and absolute guesses are sprouted out there by the uninformed.
It's an absolute pleasure to watch someone who obviously knows his stuff about these units.
Hi Ray, thanks for the positive feedback and kind words. J
Hi John, Just coming across your videos having just installed a 5Kw unit into my caravan ready for the winter. Very informative regarding the fuel hose and delivery system, since I have only once since installation a week ago had a successful run of the heater. Suffice to say, mine came with the poor vinyl large bore fuel line, which I see now I need to replace from the pump. (luckily I have plenty of the 4mm hard bore hose in my workshop). Another issue is that in the caravan, I am very limited in installation location of heater and fuel tank, such that without putting the pump outside / under the van on the chassis, it's near impossible to get a steady incline up to the feed point of the heater. What happens currently is the heater will not properly ignite, makes a very impressive smoke generator with clouds of white diesel vapour!! It's good to see from your video now how I can hopefully resolve my problems just changing the feedline!
Thanks for the great info in your videos. ;)
I’ve just installed my new heater and it wouldn’t run properly. Ran for a few minutes then went off. It came with soft green fuel line. All that happened was very little heat output lots of white smoke and diesel dripping from the exhaust muffler and E10 error message. After priming at least 10 times and trying again I watched your very informative video and have ordered the proper hard small bore nylon hose. Hopefully this will fix my issue. Many thanks for the great video…….Very helpful
I am fitting my heater today.
I have binge watched all your videos and slept on it.
I am sure it will be a well informed install now.👍
Thanks for the nice feedback Slade. JMcK
Hi John, great run down. I was about to go and buy some large diameter fuel line as I couldn't work out how the small stuff was supposed to fit. You've just saved me money and no doubt some frustrations. Thanks.
Hi Andrew, you can run standard fuel hose from tank to pump on the suction side, but should only use hard nylon small bore tube on the delivery side of the pump. JMcK
Hi John, I sure do appreciate your knowledge and your willingness to share with terrific videos. I have heard through RUclips that winter diesel is not good to use in the heaters. Winter diesel is sold here in Canada during the winter. Regular diesel will gel and can not be used in cold weather. I guess the problem is finding Regular diesel here.
@@green-zone36
Hi G,
Thankfully in Aus, we do not have that bitter weather you get in Canada.
I suggest you try running kerosene in the heater in winter.
If you have heating kerro with a bit of sulphur in it you can run it neat.
If very pure lighting kerro, and you use the heater a lot, perhaps adding 10% diesel, for pump lubrication may be something to do.
Please let me know how it goes. JMcK
I have a Hcalory heater that has never fired up, I just get an E 10 error code as well as fuel dripping out of the exhaust - as well as a duff glow plug I suspect the fuel pipe has issues, it is a combined tank and heater unit and there is a fantastic bubble collector where the tube drops to the heater from the pump. I found your content very enlightening as to why we need to use hard line of the correct diameter. i will order both and try again. when you mentioned tubes running up hill i initially questioned that but upon explanation it makes perfect sense - bubbles travel up hill so no collection points on route. The manufacturers should make these things the other way round with the tank on the bottom so that its all up hill. Oh dear i'm waffling - stay safe
How did I not think of that by my self... larger diameter, more volume to pull... larger volume, bubbles joyn... THANK YOU, not just for here but also elsewhee, moment of AHAAAAAA !!!!
John I genuinely enjoyed your video. All the detail along with the props you used and even going as far as setting up the hose display was excellent.

I think you've saved me a lot of tears showing the shortcomings of the Chinese copy, which I'll be fitting shortly to the brother in laws' motorhome. I was going to tap into the fuel tank auxiliary if it has one and use copper brake pipe as I have plenty and the flaring tool, nuts and connectors but your suggestion of 2mm nylon might be a better way to go. Many thanks.

Hi John, thanks for your great videos. I have just installed a 8 kw Chinese heater in a workshop and it works great. My heater came with a remote control and a small online fuel filter which is a lot better than the tiny filters which comes with the D2 Airtronic. It is a good idea to run the heaters at a high setting regularly to keep the combustion chamber clean. I think our diesel in Western Australia is pretty low quality as I travelled over east for several months, running the heater every day for about 8 hours with no problems and clean combustion, however, once back home it only took about 2 weeks to soot up the combustion chamber. Adding some kero and running the heater hot does cleans the soot a bit but usually I have to replace the screen in the ignition changer. I like your removal tool! Another problem I have encountered is a dust build up on the flame/ heat sensor mounted on the combustion chamber which can cause an error code. I found that the shortest length of the exhaust pipe possible will give longer periods between services, our diesel again. I have an Edith Diagnostics adapter for my Espar D2 heaters to work the error codes but have not had to use it much as I can usually figure out what causes the faults. Thanks again for you information. They are great space heaters,
Hi Peter, thank you for your detailed feedback. I agree with you about the variance of diesel quality and the need to keep the exhaust short or go larger. You also need to keep the combustion air intake short, or go larger.
Glad you like my screen removal tool, but have you managed to source the very rare screen insertion tool?
Cheers, JMcK
Truly an awesome video and demonstration. On paper, I don’t think there should be a problem with lifting fuel through a larger diameter line. The vacuum pressure at the top of a column would only depend on height not diameter. The pump would only be lifting the column of fuel within the cross-section of the pump inlet, not the entire volume of the hose. That being said, I’m taking your word for it!
You are correct. In practice, I can’t tell the difference. JMcK
Hey thank you sir for showing this effect of the soft tube compared to the hard tube. I'm experiencing leaks in my fuel line at the filter and at the pump. I'm considering replacing the soft tube that came with my heater with the hard fuel line kit I ordered

Nice information and explained very well. I will put this information into practice. You need to write the manual for these heaters as the installation instructions that come with them are hopeless. Well done.
Thanks for the feedback Rohan. JMcK
Fitted 2 in my yacht, carboned up one on second day, watched your vid and now know I've been very naughty. I've learned much from you good sir, I will go forth repair and rectify my badness! Ta very much.
👍
His advice and requirements are absolutely correct. Go to the eberspacher website and follow their install specs if you bought a Chinese diesel heater and save yourself a lot of time and aggravation
I havent watched it all yet.. but i put the fitting or a hole in the cap (dont drill out the bottom) with a length of smallest diameter hose (the hard nylone works perfectly) going to the near bottom of the tank. Mount it higher than the heater and ..presto.. the siphon effect keeps the pump primed.
Thank you John this will save me a lot of time when I install my system! You are a great contributor to society sir!
Thank you for your kind words Hung. JMcK
This is a brilliant video, I'm currently installing mine in my boat and I was debating using automotive braided fuel line. As I thought the hard nylon line would be sceptical to cracking in cold weather.
