When the HE engine first arrived on the scene, it had the same fuel rails/system as the pre-HE engine. Because Jaguar had some engine fires, they soon brought out a recall with updated rail and additional components. But the reason for the fires was the vacuum retard and fuel vapor entering the distributor via the vacuum hose/manifold. The fix was an updated blue vented distributor cap with two tubes. One had a small air filter on the end and the other vented to a vacuum source. This of-coarse stopped a build up of flammable gases in the distributor, the cause of the engine fires on the V12 HE Engine. How do I know this?. I was working for Jaguar dealership at the time and on one occasion, while working on a HE, prior the having this mod and revving up the engine, the distributor exploded into several bits. As technicians, we get to see many exciting things like this. I hope this is helpful.
So that's what that odd plastic transparent filter hanging around my engine bay on the end of a hose that goes nowhere is for! Good info - thanks.
Thank you for this video and comments.
I had injectors spraying directly on the distributor. Scary situation!
Do you think its a wise move to but one of these cars ,or avoid them?
That's great info to provide to the rest of us!
Some thing to add. Install the small injector seals into the inlet manifold prior to fitting the injectors. lube can also help fitment. Also, and important I feel , Is to have all the injectors checked and flow tested for consistency. If you have some injectors with unequal flow, it can upset the tune of the engine.Thx
Awesome video. My only comment would be not to use engine oil for lubricating new hoses, but rather 96º alcohol. It will slip incrediblu well, but as it evaporates, it will be impossible to remove. Great job all in all!
With your help I was able to complete this task with ease. Thank you
I have been meaning to comment on this and report back my experience with the product since I had the service done to a '91 XJS I purchased earlier this year. The only reason I can offer this report is due to the quality videos on this site and so, Jared (I think that's your name?) - THANK YOU for doing them.
I'm not mechanically inclined and even if I were, I don't have the garage space or tools, although I would like to learn and eventually begin doing some things. But I knew that when it came to this job, I would definitely want a professional doing it.
I live in Carlisle, PA, and prior to the purchase of the car, I hunted for a good mechanic to have it worked on, even sharing this video because I had determined it would be part of the very first service I do before making the car a regular (hopefully daily) driver car - yes, all year-driver. While I did not find a garage/mechanic with specific experience on Jaguar V-12's, one local garage has a mechanic who has worked on other V-12's in his career and after lots of discussion, I determined that I would use them - and so far, so good. And, since I'm in Carlisle (as some may know, a bit of a "car community" due to our national car shows, including the well-known, annual Corvette show), its actually quite easy to find good, experienced mechanics.
The initial work I had done included the basics, such as flushing/replacing all fluids, but also a front-end rack/pinion rebuild (which they actually sent to a union shop in Philadelphia), and replacement of fuel hoses using the Mr. Injector kit. I have two comments to report on this, which I hope are helpful:
1. Mr. Injector Customer Service: I found it to be superb. They were quick to respond to all my emailed questions and quickly mailed the product via TNT Express. After a week, the package did not arrive. I inquired and Mr. Injector reached out, only to discover that the package had somehow been lost within the UK. Not to worry, they sent a second kit to me, overnight (arriving in well under 24 hours) using Federal Express. This was no cost to me. I can't say enough about their swift, unwavering demand on themselves for excellent customer service and I hope this post will encourage others to use them so that they stick around. I wish I could leave a comment on their website but it doesn't have a section for this.
2. Report from my garage on Mr. Injector kit: The mechanic and team that reviewed the kit and installed the hoses and components, inclusive of a review of the Mr. Injector instructions and illustrations, said it was very impressive and of high quality. No reported issues for the install, as difficult as it is. Now, I just hope that Mr. Injector is still around when I decide to do the job again as this is a critical one for safety.
As for the car, it has treated me well, even in stop and go traffic (no overheating). Its more comfortable and smooth on the road than the '17 Ford Fusion lease I will be returning to Ford in October. I just crossed over 39K miles on the engine and I plan to take it back in for a second oil change and a full review of the engine in a month or two. The power steering has a bit more of a "gear" whine, I think, than when I first got it, so I hope that isn't an issue. I am seeking a place that can apply an undercoat to help protect from winter road treatments, etc.; and I have to replace the headliner and found a great shop in neighboring Lancaster County that priced the job at $300.
For those of you who have read my comments thus far, I'm curious what you think: my car is the same color as Jared's convertible '91 XJS - just a coupe, with matching, red pin stripes on the leather upholstery. I know this would not be a "stock" decision, but it crossed my mind to do the headliner in matching red and personalize it a bit. I plan to keep the car as long as I can.... so, I thought, why not? Should I, or should I keep it the same beige color?
Thanks again for these great videos.
Ah that „Bing bling“ noise when a screw falls deep into the engine and is never been seen again.....
Thank you for this very good explanation of this complex repair job. It persuaded me to do the replacement of the 33 year old fuel injector hoses on my 1987 XJ12 SIII HE myself. Not sure I would have dared to do so without this video.
Great video! As these classic v12s age they can be an accident waiting to happen! Great Public Service to owners!
Thank you once again, I had no clue where to start before, but this would definitely be within my capabilities
With a good kit it can really be done at home. It's a satisfying job too
thank very much .. Very important for me and my Jaguar XJC12!!! Jaroslav from Czech Republic :-)))
Your car collection just oozes class and it's awesome of you to put so much work into these videos
Thank you Jason!
Thanks so much for this video! I just did this service to my XJS and this video was extremely helpful! Incidentally, I found out through a web search that this service costs approximately $6,500 at the service shop. Your videos have really given me the confidence to service my Jags on my own.
It’s 8 hrs labor and about 5-600 in parts at most so not quite sure who’s charging $6,500 and what dummy is paying it 😂😂😂
Nice instructional video! I have a similar Bosch system on my Bertone X1/9 although thankfully, only four injectors instead of 12. One of the biggest mistakes I see is people using a sharp utility knife to split the hose longitudinally inevitably slicing a groove into the metal barbs beneath. Then after reinstalling and pressurizing every connection leaks!
what a job. I can imagine some mechanics missing bits of this job. You really need ones you can trust!
If you want a job done proper, do it yourself. I have learned its impossible to keep an older car unless you work on it yourself.
Great video, great channel, keep it up! I own a V12 Jaguar and I really appreciate the information.
You're welcome! Glad you enjoy them 😃
wow now thats way easier than everyone in the the group made it sound, they kept saying you needed a crimper and special tools, damn this wont be no harder than doing all the Injectors on the 750il V12 did. more time consuming for sure and more steps but still easy. you sir have givin me new found confidence!!
It can really be easily done at home. Just takes some time
Great presentation of the work required. I’m doing an XJS next week. Thank you
I certainly agree with the importance of doing this. My 89 XJS suffered a engine fire 5 years ago. It had original 89 fuel lines with the date stamped on. It had sat for years prior to the fire. I would however caution with your technique of cutting the hoses off the way you describe. Great potential for messing up the barbs on the injector. Happy to say after 6 months of constant gardening it is on the road again. Increadible GT vehicles! Thanks for the video man.
Thank you Brian! Yes you need to be careful but it has worked for me. They truly are great GT cars that deserve a lot more love
Thanks a lot. Really useful . I had a Jaguar XJS V12 convertible 1989 back in 2016. It caught fire due to old (never replaced) fuel hoses which leaked just above the distributor. Fire was put out quite quickly but no dealer or garage would repair it with guarantee and it was taken over by my insurance company. Now I bought myself another XJS V12 convertible (lovely car !!) but from 1990. I also bought the repair kit you recommended and I will follow your instructions and change all fuel hoses before summer.
I'm glad you're changing the hoses! I hope that no more of these great cars end their life in flames
Very happy to have discovered your channel. This job is on my to do list for my 1980 pre he .
Very helpful insight into techniques 👍
Thank you Brian! Best of luck with your pre-HE! I have a series on the fuel injection system on those cars here too :)
I think I love my carburettor version of this engine even more now. Much simpler to work on 😂...
They are much simpler to work on 😂
Great information and detail. Love it.
A very detailed instructional video, makes me wish I had the opportunity to try this.👍🙂
Thanks for a very informative and detailed video.
Love these videos man! Please keep them up
Thank you Joshua!
Great video - look forward to these each week, yes to the remaining fuel hoses.
I have tower seal ready to go, Oh and spark plugs are sitting on my desk.
After that fuel lines.
The engine bay will be like new then!
VERY IMPORTANT VIDEO, PURCHASE A SM CHEMICAL FIRE EXTINGUISHER, KEEP BEHIND PASSENGER SEAT. SOME U.S. MODEL XJS HAVE FUEL CUT OFF SWITCH UNDER SM VENT DRIVERS SIDE.
I would recommend to measure resistance first before rebuilding as a basic sign of health.
this channel is so good. You help me again and again
Thanks! I'm glad that you like it
What an excellent video, Adam. I'll certainly look at mine and replace if needed. Thank you.
I’m glad you liked it!
@@LivingWithAClassic 🙂👌
Wow, just wow
Great video. Wish you could've went over wrench sizes etc tho.
As you mentioned about the sparks which may come from cracked spark cables, it is also advisable to by a new set of spark cables!
Yes it's good idea to change those often
Great vid👍🏻
This a very informative and DIY video and a must for fuel injection Jaguar owners 6 or 12. My fuel rail was replaced on my V12. The mechanic did not use the kit shown here. He replaced the short injector hoses with correct ones that were simply pushed on then used two fuel injector clamps per injector. My V12 runs silky smooth so that method seems to work. Its nice to know that a rebuild kit is available since rebuilt injectors with hose are sold by Rockauto in USA for $30 each plus $10 for core. There are dangers of fuel injection on vintage Jags unless these critical items are replaced or overhauled as this video shows. Time consuming at least when your wife smells gas on you she knows where you been.
The kits really make this a job that most can tackle at home if you don't have a trusty mechanic.
It's always good to come home smelling of gas, oil or transmission fluid, the wife knows you are safe in your garage.
A lil tip for rubber I use AT-205 RE-SEAL in a spray bottle to rejuvenate my under bonnet and under car rubber it prevents the hoses going hard because like internal Engine seals it replaces the lost chemicals in the rubber lost during heat or aging........its what I do n my XJS V12 all the best and thanks for your great videos.......
I will have to try that product!
@@LivingWithAClassic I have seen a 25 year old headlight rubber trim as flexible as if it was a day old rubber.......good luck mate!
Really shows the difference between British and German engineering. Nice job! Thank you!
Replaced loads of these kits in the workshop in the uk, factory time under warranty.
Our kits came with injectors already fitted on the rail, never had to do all that.
Used TQ oil to lubricate.
Must of been much faster with the injectors already in place
@@LivingWithAClassic
Still couldn't reach the factory time alliance.
Injectors are my next bigger project on the XJS, 86 then the cooling hoses.
I just replaced the Aux Radiator fan motor and blade (Factory CFM is about 650cfm )- all replacements were $350 + USED! and i did a lot of research to find replacements including Bosch which the old was but had been replaced im sure- after painstaking cross checking MANY $24 type kits availible online i found that Mishimoto has an 11inch thinest of 3 they offer at $89 - had 950 CFM as well which was such a improvement for cooling-old 650cfm ( I read where a longtime jag owner said to wash all radiators really well to remove any blockages from sandwiched fins as well) so, I ground OFF the outer composit brackets and corners in my bench grinder/ wheel, and it fit snugly but went right in to the venturi of the sheet metal frame! i removed all brackets of the old one and saved them in case i ever sell the car and some one wants original. My goal is Original except where $$$ is so high i cant find or obtain the replacements with out a 2nd Mortgage. The look is good, performance improved and wiring is very straight forward. Next Electrical will be to replace engine area fuse block and holders with modern blade type. Appreciate your clear views and instruction on the projects you do! can't wait to be driving this car thanks to your motivation! Plus several folks are asking for a ride in it --one is the former owner, she's the grandmother of the Friend who told me about their selling it in the first place. Cheers :)
It looked a daunting task but thanks to your excellent video it wasn't. My filters were very hard to get in straight , lots of rotating & eyeballing needed to get them true,& just would not go right in until, with some trepidation, I resorted to the bench vice. Easy! No damage to the filter end. Thanks also for the gearbox filter change video, new fluid has improved the 'lazy' gearbox. The car has only done 38k miles in 37 years & I suspect only one previous change in that time (judged by chewed bolt heads!)
Forgot to say I also have a 1965 3.8S so very interested in your restoration. It also has just 38k on the clock.
I know for sure I'm going to be doing this with my '78 once I get it. Nice I can do it with the tools I have :).
It's the best things you can do to your car
Great video! Very helpful! On the topic of fires, I’d love to see a video on Malleri ignition system and preventing cat fires!
I covered that topic a bit in my video on V12 ignition systems. Thanks for watching 🙂
Danke!
Thank you for the support!
I assume thats the same for a 6, think I will give it a go on my 83, probably about time. Thanks.
In the United States, we add Ethanol to our gasoline. We must consider that the corrosive effect of this additive does damage to older hoses not engineered for Ethanol. Along with replacing your old hoses, use non-ethanol fuel if you can find it. Your classic will run better and have less long-term damage.
Excellent video! No need to make the ferrules tighter?
Great video! What length did you cut your hoses to? I know the front two injector hoses are a little bit longer.
Hey adam great channel and great video.
I'm about to do my fuel injector and i only found those kits on Ebay, are they good for this job ?
Great video... I am about to dp this on my HE XJS. I still can't quite work out what the metal sealing rings do? They dont even get crimped so I dont see the point in them and don't understand what keeps the hoses on tight? Am I missing something here?
Safety first. Always disconnect the battery before conducting any repair work on your vehicle. Some wires remain energized even if the vehicle is switched off.
I love Jags but that engine has so many bits and parts- making it a nightmare to service. I am amazed that Jaguar back in the day was ever able make those engines, and still make a profit.
My only complaint is that you never said to make sure the brackets are facing the right away and I didn't notice they had to be on my own. I just got all done with everything and put it back in the car and tried to put the injectors back in but I can't plug it back in with the brackets facing the right way
So I have a question. I have put 2k miles since start up and I have everything apart now to seal up all the leaks and poorly running systems. Noticed gas pools in 5 of 12 sparkplug wells. ( yes I am aware how fortunate I am) I look and some of my fuel injectors are not entirely flush and evidently the gap enough for fuel to most likely dribble out when off. Everything looked right. And fastened down correctly at the time. Any ideas? All I can think is to lift it all up and try to reset again. If that does not do the trick I guess I will just have to buy the kit, even if I was off slightly in my lengths of fuel hose there would have been enough stretch that the locking plates would have forced the injectors flush? Very glad to be as OCD as I am I now know what correct should look like. I would have been gutted if it burned down to the ground after so much work and promise. My guess it won't be on the road again until summer. It will increasingly much better though. Just in the weeds right now. It is starting to look like I am wanting to take the engine out! Thanks to you and the information age this car will see me out the door someday. 89 xjs 35k miles
Revisited this great vid...want to do this on my 90 dd6...tried Master Injection UK - seal kit 131, alas, no one home..still down re. covid I guess. Still, thks again
Hope they will be able to send out kits soon again. Always been very happy with their service
Directly call them. They kindly helped me out by phone during the lock down.
I was able to order the kit from MrInjectorUK , you must use the masterinjectoruk@gmail.com email for order.
Have you ever had any issues with I believe is like an egr rails the rails right by the fuel injection rails one side on my 85 xjs gets very hot the other side I can put my hand on while running but driver side will burn you if you barely touch it any help would be appreciated
Great, does the pre he require the use of clamps to attach the injector hose as well ? Great vid as usual 👌
Yes they do. Some years had just one clamp and a normal fuel clamp on the other end and some years had these special clamps on both sides. I can send you a picture of what it looks like on my XJ12. It's all pretty new there too
My injectors seem to have metal clips holding them on. Any ideas how to disconnect these? Is it just use a small screwdriver?
Thanks for the advice. It's very helpful. Is the procedure the same for the V12 of a XJ12 S3?
Sorry about the late reply but yes it's the same procedure!
How do I find the u tube for the other fuel lines to change ?
I have a '92 XJS V12, and the injectors do not have these tubes. The injectors are directly connected to the rail. I will need to replace the large input and output hoses, at some point.
Yes it was changed with the facelift and changed once more before the end of V12 production I believe
My garage in view of a MOT is telling me that I should replace the injectors and the full fuel rail (perhaps since they think changing altogether it can be easier), but not on the engine you showed, but in a 1993 5.3 one, ie the one with the injectors directly attached to the rail with a lot less hoses. This, in their view, since they found a bit of fuel “humidity” right besides the visible part of the injectors (the one that you see when they are still there). The pieces are all original from 1993. Does it make sense to you ? Thank you very much for your support.
Do you think that in a hot latitude, (Florida USA) the 12 cylinder cars are extra disadvantaged because of how much heat they make under the hood, combined with the way the various hoses and wires are snaking all around, and, being subjected to endangering heat??????????
I'v just realised that the answer is in the title!
Glad you found the answer and yes it's the same
I have a 1990 Jaguar XJS V12. The fuel lines EAC 9987, 9986 and 7983 the rubber between the metal lines is brittle and needs to be replaced. I checked to buy new and are close to $400 USD. Is there a way to replace the rubber or the lines without buying these new lines?
I think instead of doing all of that on my xjs im just going to go the dual carb route
Great video. I'm planning on doing this very soon with my v12. One question I have though. Has anyone ever thought to replace the rubber hose with steel or something more heat resistant? If this is a common problem maybe a steel fuel line could be a permanent solution?
It's the connection between the steel fuel rail and the injectors that are rubber. On newer cars this is just an o-ring and less prone to leaking
@@LivingWithAClassic Exactly - I bought an 1993 5.3 XJS one month ago, but I cannot literally find the "hoses": the trail is kind of "directly" connected to the injectors ... is this what you are referring to ? In other words, I do not run a high risk of fire...? Thank you and keep working with your channel, really helpful.
hi, thanks for the video. Where can the tubes and the whole injection kit be bought? Thank you Hynek.
Get it from Mr.Injector
Thank you. Will it also fit the XJR-S 6.0 1990 Pre facelift?
is the same injector kit used for the PreHE and HE?
It is a different kit since the hoses are a bit different. The website has a kit for pre-HE too
Do u do all jaguar like x300 xj6??
I don't own an x300 but I would work on them. They are great cars!
Make sure there using modern rubber materials as e10 fuel rots traditional rubber
Yes it's very important
This doesn’t apply to the 94 xj12 or does it
The fuel connections are a little different there but it's still very important to check the fuel lines
Come on who does not replace fuel lines on an oldbcars it one of the first things all classic car owners
My XJS just burned in the highway...Good bye.
Why dont you call them spanner as a wrench is a different tool
A spanner can be double end single end, open and closed.
A wrench is a single end with an adjustable.
I have a new project XJS 1985. Was told that ir ran when it was parked 5 years ago. I just connected it to a jump pack, and it cranks over, but nowhere close to starting. It probably has 5 year old fule or no fule at all, so I plan to fill it with some fuel. Before I do, I am not sure about one line in engine that looks like a fule line and fule filter, but have no idea where it goes to. ANy suggestions? Maybe it is not a fuel line, but sure looks like a fule filter. I just found that I cannot post a picture. SO maybe this link will work. drive.google.com/drive/folders/1fN4FBNDoiv_GcDIYt9mD6T-8j2Aooe7H?usp=sharing
That is a vacuum line for the the distributor. It’s to ventilate the distributor cap
