I stuck mine in a mayonnaise jar, used cable glands at either end for fuel lines and sealed a slit for wiring with silicone...then filled the jar with sand. Then wrapped the whole package in insulation. Good to go. Can barely hear it.
Love it that your bench has a random washer, an offcut of insulation and a snipped tyrap on it……keeping it real 👌
I only tidy if I absolutely have to.
Cheers Mr Mcluckie, what a great test! Really appreciate the time and effort you put into your video's, keep up the great work!
Just wanted to say your videos have provided me with invaluable info on getting my heater install perfect. Thanks mate 🍻 🇦🇺
I switched over to the Green type pump last year and there is a noticable difference .
I also suspended the pump underneath my campervan in what could be described as a spider's web of thick elastic, all fuel line is wrapped in foam anywhere it touches the bulkhead.
I now sleep soundly. 👍
Great idea but when you sleep near a quiet neighborhood, it can be bothersome to the neighbors .. we put our inside the van for that reason
Super! Thank you for your effort and your videos!
Awesome, thanks for doing the test. As always will save a lot of people lots of time and money doing all this themselves. Cheers again mate.. :-)
James' pump is brilliant. If you want quiet pumping for a diesel heater then that's the one to get. I've had mine for a couple of years now and after changing my diesel heater it needed to be wired a different way. Even after the length of time I have had my pump, James still gave me support and the pump was re-wired within 30 minutes. Excellent pump and brilliant support from James. Well worth the investment. Can't thank him enough and love the videos from David - they have been very helpful!
Hi Dave thanks to you I connected James after your first vid.
The pump is excellent and more importantly guys like him should be encouraged and supported. Hidd so pump Cost is quite insignificant compared to cost of a full van build.
I’ve requested this before after seeing another comment on one of your videos suggesting it, but I’d just like to suggest again trying running the pump submerged in the diesel. I suppose I should just try it myself but I’d rather someone else risk their pump😁. Thanks David for making this useful content like you do.
Thank you as always . I think testing at low pump speed and mid speed would be useful as users requirements are different. I'm particularly interested in encasing the pump in silicone, and also one reviewer recommended encasing in a bottle of sand. It's a case of finding the best sound deadening material for the required pump speed.
What constitutes 'sound' and what is classed as 'noise' are very different. Sound can be measured and analysed whereas noise is a very subjective thing and, not only different for any two people, but also to one's self under different circumstances. My best way of defining 'noise' is 'any sound that is not wanted or tolerated at any point in time' If you are in a workshop or concentrated on other things, you will hardly notice the pump at all. If you've had one too many coffees and are trying to get to sleep on a quiet night, it could sound like a jackhammer. Once the brain locks onto a sound and labels it 'noise' it will start to concentrate on this and block out everything else. Then it becomes a problem for 'you' though might not bother the missus sleeping next to you
The more you try different things to quieten it, the more your brain will tend to amplify what sound is actually there [even if it measures less] and it could easily become an obsession .
For me... Fairly quiet pump in a van and couldn't give a monkeys in the workshop
My pump is mounted under trailer, that's right under my bed, I can definitely hear it but after a while the ticking just seems to go away, but for the price might try 1 of the green ones, in the test the sound of it ticking didn't sound as harsh. Good video usual David
Mine ticks away nicely to "Me And Bobby Magee" it's a keeper 🤣
I bought one of James Browning Smith's custom made diaphram pump. It's simply dead quiet and worth every penny. 17 days from ordering to my doorstep in Seattle. 👍
How much are they?
I swapped to a green pump and can barely hear the pump at all. Made enough difference for me
Honestly, the ticking of the pump is the least of my issues. Inside, it's the loud roar of the turbine fan, and outside it's the loud roar of the combustion air inlet & exhaust that are loud as heck.
Can't even hear the pump over those 😂😂
Great test! I don't find the normal pump that bad, because there is already so much fan noise. I could see if this was remotely mounted and the pump was near somewhere you sit, it could get annoying. Really cool that the nicer pump is actually almost totally silent!
Could be interesting to have a spectral analysis of the audio. To my ears the “silent” pumps have more low frequency components that could be easier to damp out with other methods. The stock one seems more tinny and clanging.
Like others i have tried different setups with different pumps and spent many an hour or day trying to get rid of that mind numbing tick tick bloody tick. The only one that works is the one referred to as "made by James" really good does what it says. He has improved the design over the last year or so to sort out a few problems. Bit pricy but well made. And excellent back up service.
I don’t suppose you know how much he is/was looking for these ? Thanks
as much if not more than the price of the heater itself.😮💨 have had this one running for 2+ years and its still going. cheap heat and a good nits sleep
The main differents to me is its a lower frequency, not just less volume than normal pump, much less annoying for me. buying one now!
I noticed that as well, not just quieter but duller. :)
3db is over a 50% noise reduction. I'd say it's a good buy. Along as it lasts and delivers the same amount of fuel. For all we know they just took the standard pump and put 2 o rings on either side of the cylinder so it would pump less fuel with each stroke. Or maybe it's a rubber that will degrade with fuel.
But assuming it's fine that should be a good purchase. It seems significantly quieter. And any good mounting on the standard one does a pretty good job already. I'm sorta interested if the more exspensive mufflers that arnt straight through but look almost identical are worth it. The exsaust sound isn't the most pleasant for tent camping.
Excellent stuff! respect! To me the newer green "silent" pump sounds a hundred times better! Can hardly hear it with headphones on listening to your clip, likely just a duller thud, not a tinny twang, twang, twang. Will be buying one now. Cheers
Hello, did you buy one and if so, how did it work out? thank Trevor
Nice work matey.
Perhaps a Wikipedia link to "comparative" might be helpful for some..
Will have to do some open hear surgery on mine soon as the fan has started to rattle.
But not until it warms up in NZ as parts will be a pain as traveling around.
Have thought that using a section of pipe sleeved over the pump and filled with silicone would be a great silencer..
May be a few months before I try this and I don't have sound meter as my phone is so old it's made of wood.
Have a good one mate
Cheers Dave
The green type are much quieter overall I have found with mine especially once over 3.0 Hz very little to no noise at all from mine but unfortunately while quieter still noisy at low 1.5 HZ pump speeds. SO if you live somewhere very cold and need to run heater at a higher speed definitely worth purchasing the green quieter type.
Good point. Need checking at different pump speeds. Mine runs on 1.3 all the time do maybe I need a different solution.
Excellent informative video. That clucking, clicking is a pain. But I think I'll save abit cash and find away to dampen the sound.
Our 2021 conversion came fitted with an Eberspacher. I’ve no idea what type of pump they use but it seems to be a completely silent fuel pump (at least I can’t hear it at all). The heater still sounds like a jet engine on full reheat though… ;)
Would be interesting with a comparison with the Autoterm TH11 super silent pump
Replace horrid white nylon fuel line with reinforced rubber fuel line ( 3.2 mm I.D ) for a much softer tick , heavier line , less resonation and 50% less joins and 'faf' which can potentially result in problems ect ...
I bet that's not popular due to all the 'urban myths' that surround these appliances 🤣🤣 ...
Luv the videos .
I have James pump it’s great you can’t here it at all it’s under my bench and it hasn’t let me down I have 3 desal heaters and had to replace stranded pump 3 times in 2 years but in my Motorhome no problem works every time
Before my installation, I watched alot of sound suppression videos, ALOT, some from sound engineers, the one that came out on top, above dedicated expensive foam, egg cartons, bubble rap, factory casings, the lot, was quite surprising, A BEACH TOWEL, if the area is suitable, I'd reccomend raping it in an old folded beach towel, works brilliant. Hope this helps.
Good test David and love it that you are making these videos (thanks). But pish who needs a silent pump - the sound of a eberspacher pump is the sound of warmth. It sooothes you to sleep and gives your babies (and puppies) a sense of maternal comfort. Are the chinese diesel heater pumps that much louder ?
Thanks David.
I used a sole from an old pair of rubber boots as a bracket it is under the floor and it cannot be herd over the noise of the fan , super . Where is the best place to get replacement controller. One of mine has stopped working. Cheers, John.
You should have tested them mounted suspended and vertical or diagonal as per instruction manual, so they guaranteed get bleeded from any air pockets This test sounds like they are pumping air. My Planar pump looks like the green one and is inaudible, I have to feel to check if it is running. Love your channel.
Just because I don't film me standing there bleeding the air out of the pumps doesn't mean it didn't happen. Oh you should hear them on camera when they are pumping air, sounds like someone hitting the test bed with a small hammer.
@@DavidMcLuckie
Should the pump be vertical or horizontal then?
Very interesting comparison video.
A gyrator style pump with a stepper motor would be an interesting test as well, but I'm not sure if they are available.
I have seen some pumps that run a speed reduction and a diagram to pump various chemicals. I also wonder if something like that would calm noise a bit?
The blood transfusion type pump would be a good start.
@@chox2001 Peristaltic I think you mean.
@@roygardiner4002 that’s the word I needed 👍
There is product called sound mat.
I wonder if it would make a difference.
There is insulation called "safe'n'sound".
This insulation i know really works plus it is fire proof. Like you can use a blow torch on it.
Rockwool is the company.
Cheers from across the pond.
I zip-tie dish sponges around mine then lag with self amalgamating rubber tape, suspended by more zip ties, seems to cut the noise down by about half.
I could barely hear the non standard ones over the sound of my own diesel heater running in the background!
Nice. the filter one could be good. I don't find it a problem. mine is mounted under my bus using the rubber mount and I always find the fan/air blowing out louder anyway even on low.
Thought the same, pump noise is noticable for a short time but then the fan and burner kick in which drowns out the pump. Anyone modded one of these to run almost silently without a giant insulated box?
With the available rubber/silicone pump insulator housing around it and it hang mounted by a loose ziptie my standard issue pump is about 95% silent next to my tent. If it was outside a van i wouldnt hear it at all.
Thanks for your very informative video. I am running a race honda motor which came with a loud external Weldon fuel pump and race fuel tank. Im looking to replace my loud weldon fuel pump with something quieter. What would you recommend. I mainly do street racing, nothing professional. I greatly appreciate any recommendations. Thank you in advance.
Hello.
Great videos on the diesel heater, this one in particular was interesting. Have you tried or considered reviewing the new upgraded exhaust too, if that to is quieter then the chinese heater manufacturers are seemingly upping their game.
New exhaust?
Have you noise tested the bog standard pump in the pink "silencer" housing yet?
Would be nice if someone made an open source design for a peristaltic dosing pump and a 555 timer driven MOSFET circuit which I suspect is all James' pump is. It's on my list of things I need to get round to doing.
Hello David, thanks for all your excellent video’s.
I hope you have the time to answer my question, is it possible to mount the heater vertical, with the cold air intake down, (or the cold air intake up). The most convenient orientation is vertical for me when possible.
If it is possible, what should be according to your knowledge facing down? (Hot or cold side)
Thanks again for all the work you put in too it,
Regards Hans
Theoretically yes. If you point it hot end down it would be much less likely to leak diesel from the flame starting hole (at the glowplug). And should it flame out it won't fill the burn chamber with unburnt fuel.
@@DavidMcLuckie Thanks for your reply!
Content ideas:
1 preheating fuel.
2 exhaust length requirements short long advantages and disadvantages
Great test, thanks, David. There is a Webasto or Eberspacher separate fuel pump "damper" available for about 15 bucks.....i wonder if that works?
he has a video testing that 👌👌
@@nextellcup8 Yep, i realized that later, thanks
Hi David, are the smaller capacity pumps quieter? Or at least more frugal?
Wonder how The Autoterm TH-11 metering fuel pump would compare. It is the quietest piston pump out there.
I want to see the self powered diesel heater with turbine, without diesel heater, only the starter-generator turbine.
Best regards! 🇧🇷
The 2db drop from the green pumps was quite noticble to me. But like you say, are we hearing it correctly. For me, the bigger problem is the exhaust noise.
Get a webasto silencer. It will kill the exhaust noise :)
@@krimke881 thank you for the tip. Just need another mortgage now... 🤣
A guy recently on RUclips added a Chinese exhaust silencer to the air intake tube, just after the filter and it really quietened it down, a lot of noise comes from here.
Hi David 😄 I was thinking of installing a diesel heater in my motorhome in the outside side locker. Can it be mounted on it's side and horizontal the exhaust and intake going out the back of the locker?
It can be mounted on it's side as long as the glowplug ends up on the top side.
@@DavidMcLuckie thanks 👍
Which size pump do you need for a 5kw Chinese diesel heater, 12v 22ml or 12v 28ml?
22mL size.
Hoi is zo tillen pomp .nog tekoop ?
Oh and what difference does gravity feed make to these systems?
The silent pump from James is worth every penny as far as I'm concerned it's completely silent all you hear is the heater, the knocking noise of the standard pump drove me mad , I don't know how people put up with it
Through my laptop speakers (tinny terrible things), the aliexpress "silent" pumps do seem to be a lot quieter, but that's probably because my laptop can't replicate lower frequency sounds, so could be thumping like a neighbour's bed headrest on the wall on their "special night" for all I know... :P
Aye, I couldn't hear them at all! Thought the end result was going to be more impressive, haha. So glad we have this wonderful man to test all these things out!
David - have you ever tested much longer exhaust pipes to see how long you can go? Maybe use a bigger diameter as the distance increases? Is their a limit to length? I need to install one which will be nowhere near an outside wall. Do you think it will be safe just to discharge the exhaust inside a very large leaky old warehouse or will everyone die?
If I run a diesel heater in the workshop (properly tuned), it produces about the same CO as my Fireball diesel heater (which recommends ventilation) which is supposed to be used indoors. It registers on the Fireangel CO meter, but it has a proper exposure vs time gauge and the diesel heaters never make it to dangerous levels. Compared to a petrol generator which will set off the CO alarm within minutes.
A lot of people forget that it's exposure over time. A little CO over a long time will not kill you. A lot of CO in a short time will.
@@DavidMcLuckie
Thanks!
I guessed as much. People run car engines in garage workshops often enough. Our place is huge with 30' ceilings and is very drafty! And yes I have a Kerosene space heater which is bound to chuck out far more CO than that tiny thing.
I ordered from Amazon a webestos white hard fuel line and its inner diameter is way smaller than what is on my heater. My question is WHY? Wouldn't it restrict flow and or stress the pump out?
Im looking for the best source for the correct size white fuel hardline.
Not really no. There isn't any real pressure in line.
David.
Have you tried running the exhaust via a central heating radiator pre exhaust?
I haven't but many, many have with excellent heat recovery results.
@@DavidMcLuckie Great. Waiting on a cheap 8kw coming, or is that 5?! Lol
So two inputs to the radiator and both outputs to slow the gas flow and reduce resistance. (Testing on a single panel but if effective I'll buy a double panelled radiator- 400x600)
Does gravity effect the pump flow as my tanks will be much higher up?
Solar panels powering the electrics but may also attach peltier's to the radiator. Any advice on which peltiers to look at?
Thanks David
James' silent pump was not on the black metal box, which acts as a sound board and amplifies the sound, so was it a fair comparison?
It doesn't have a metal chunk inside slamming back and forth so it wouldn't make much difference, totally different operation
The new fuel pump is working but the eberspacher D5WS seems to be flaming out after it's start up routine. I see 052 and 054 error codes. I've had it apart and cleaned it, tested the glow plug and flame sensor all seem fine. It goes through it's start up routine and I can feel the glow plug heating up but then it shut's down with a puff or white smoke. I'm a bit stumped as to what to try next. If anyone has any ideas please let me know.
052 - Safety time exceeded. Unit failed to start on both start attempt sequences
054 - Flame cutout in high power, medium or medium 1, medium 2, medium 3, low power
The fuel pump is actually squirting out fuel, and your diesel is diesel?
Both fair questions 😂
I changed the fuel pump for another one from a more reputable seller and the heater is working. My conclusion is the other pump was not pumping enough fuel.
In a cruel twist of fate the boat the heater was being used on caught fire last week. The fire was caused by an an electric heater !
I have an eberspacher D5WS 5kw diesel heater. The fuel pump makes a ticking noise but does not pump fuel. It does not appear to be servicable (casing is crimped) To buy a genuine Eberspacher replacement pump is £250. Can I use a cheap chinese replacement pump? Any recomendations on where to get one?

@@DavidMcLuckie many thanks :)
Personally I can't hear my pump over the heater fan. My pump is mounted outside my van in the rubber P mount. My heater is a 'Belief/Tuite'
apparently the older you get the deafer you get, so dont buy a diesel heater until you reach your 60s 😂 my diesel heater is out side on the wall of the house inside a plywood custom built wall cupboard inside that cupboard is a small plywood box with the pump mounted inside hanging by 4 loops of 6mm bungee cord (available from B&Q) it is very quiet at different settings the higher the setting the less you hear it indoors, around 3.5 to 3.8 Hz is the best and 1.7 hz is the worst, the sound seems to come through the cavity wall in the hot air stream, not a lot can be done about that except for turning the TV up slightly louder. its a bit of a trade off but bearable if you want to keep warm cheaply hacking 40 quid a week of the gas bill makes me tolerate the pump tick and I just turn the heater off before bed.
I have just ordered My second heater, the other in in my camper.
This new one is going into my house instead of paying nearly two hundred dollars for a six by four trailer of firewood which will last about five weeks if I'm lucky
So, the silent in the box with the knob. Has to be adjusted all the time, or just once to pair it to the settings of the heater? if it's set it and forget it, then it's absolutely not worth getting any other alternative tested. You can tweak the installation as much as you want, on the standard pumps, but you shouldn't have to. It shouldn't a masters degree in mounting a pump to shut it up.
The knob is just for ultra fine tuning. James sets them up depending what size pump/heater you are replacing.
You’ve missed a trick. Nuts? How far can these be taken apart to clean? Can see nuts! I’ve replaced THREE pumps this year after not using heater over summer. Yes it’s only 30 quid but over 10 years that’s 300 quid. i’d rather clean them. David is it possible to clean those pumps?
Excellent question. I shall have to investigate for you.
@@DavidMcLuckie Your a good man David. certainly appreciate it.
What are you running through them to get that jiggered?
@@livestock9722 Biodiesel (actual, not wvo) Now running just diesel but with 25l of the stuff still here and diesel getting proper expensive I’d like to carry on getting rid of it. It’s fine on 60/40 mix. Will actually run B100 but the stink and smoke for the first 5 minutes is horrendous, especially if your in supermarket car park and everyone thinks your vans on fire.
@@jobbingactor Ah I see. I wonder whats in the biodiesel to make it jam up? I've run kerosene through mine to clean the burn chamber, and my high quality pump seized up due to lack of lubricity.
What's in the box one? Can we get a teardown?
There is a circuit board and a peristaltic pump. I won't be doing an in depth tear down on that.
Quiet fuel pumps are not quiet, save your money , suspend the pump in a wood box lined with roofers lead ... total silence
That’s what I was thinking. If you take the quiet pump out of its little case, how quiet is it really. On my semi, the pump is outside near the fuel tank and you can barely hear it.
Yea their quieter than stock but not silent ebay sells them aswell
Kinda surprised no one's developed a gear pump for this application. It would be completely silent and could dose accurately. The only issue would be priming, but that's not exactly an insurmountable engineering challenge.
Would need some kind of circuit to translate pulses into a steady voltage output.
@@DavidMcLuckie oh, ya totally... also some kind of encoder and control circuitry to keep a steady dosing rate, and maybe a special priming mode that runs the pump at super high speed to develop a vacuum. Might try building one this winter. :)
Also, love your videos so much!
Put pump in bucket of water. Or tube gallon of crisco cooking oil. Can you run a . A test. We ran a chainsaw muffler threw bucket of water.
I hang my pumps from bungee cords,,,barely perceivable !
Hey. I can't find anyone to try this. But I picked up 72 liters of waste veggie oil that has sat to remove water. Then was filtered to 1 micron then was spun in heated centrifuge. The 17 liters I added about a liter of gas and splash of acetone and just shook it. Hopefully shook it enough. Right now it's running my diesel heater. If it keeps going and I run through all 72 liters doing that same mixture I'll check inside for build up. (I know there's some in there from when I was adding waste oil to it last year.
It's biodiesel. It's not like what people have tried. Oil right off the shelf
You gotta filter the gunk out that will gum up everything.
Added note. 4.5hz 4500 rpm body temp is 400degrees f
Nice! I hope you saw my comment it was deleted maybe because of the link in it. But sounds like a lot of people are interested.
I did not. Hopefully if you reply here I'll get to see it this time.
@@DavidMcLuckie okay but you tested it anyway. There is also an new exhaust for the diesel heater but I don’t know if this is really better like the new fuel pump. 😂
I make my pump silent by...
turning it off.
I SUSPEND MY PUMPS WITH A BUNGIE CORD,,,I REALY HAVE TO PAY CLOSE ATTENTION TO HEAR ANYTHING
COVER IT IN SILICON !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
