We used to get a fair few k-jet cars in with running issues and non-starting that other garages couldn’t fix. The majority were down to that banjo filter.
Knowing dealer servicing most likely they didn't even remove them
@@GreyGooseRestorations I really appreciate you sharing your knowledge of K-jet. I’m familiar with the basics of it but it’s been a good 16 years since I’ve looked at one. I’m about to embark on mk1 16v swap so this series is perfect 👍🏻
@robinlaker any problems just ask 👍
Again great vid. Thanks
Thanks 👍
Love these videos and the fact you are happy to share your knowledge.
This will keep so many of these cars going for many many years that otherwise would be scrapped or used as parts cars.
This is the kind of stuff that could be lost very soon.
But now shall be pasted on👍🏻👍🏻👍🏻
Thanks, definitely I've had a few people who have got cars running after a simple fix off the back of one of my videos, best was a Ford XR4x4i - 20p O ring later and it runs
@@GreyGooseRestorations it’s amazing we’ll done. Once it becomes a fuel issue that’s hard to find those cars just then sit until they are scrapped! 👍🏻
@simonmenzies3142 exactly and we can't just been wasting classics these days, need to be saved
Great stuff as usual 🤙
Thanks
Absolutely brilliant video. Nothing worse than doing a restoration and the engine runs like junk. I will add this to my restoration list of things to do !
Thanks
Thanks 👍
Great video info sir. Hope u can show us about warm up regulator electronic. Where to buy and best ones
Another great video 😀 did you know there is another similar filter inside the supply tube (blue pipe) of the main fuel pump housing from the tank? Where the short 7mm to 11mm connecting hose pushes onto the pump housing
No but i will look now, thanks 👍
10/10
Thanks
Yet another great video, thanks for sharing!
One question, you sort of advice to remove the filter in the banjo bolt, but what about the others? Would you prefer to replace/clean them or rather remove them all at once?
Obviously provided everything is in good shape at the fuel tank/fuel lines and the normal filter is serviced as intended.
Thanks, the banjo one should have been removed at first service so its not actually required.
The other ones inside the metering head are a case of when they are at the point of requiring replacement is when the metering head is displaying issues fueling correctly and needs to be rebuilt.
@@GreyGooseRestorations Ok clear, but would you then replace our just remove the ones in the meeting head?
Much appreciated
@tubytom the ones in the metering head need to be there so it would be a replacement.
Where can I buy these filters, especially the central one that sits inside on the metering head.
Missingparts.de is the best place
That filter in the banjo bolt gave me a headache a couple of years ago! It all started when I decided to chuck injector cleaner in my fuel tank. It wasn’t long before I started having problems with the car holding back at hard acceleration. After playing parts darts with the ignition system someone on a forum told me about this filter. I removed it and the problem disappeared.
Injector cleaner caused me some issues on kjetronic a while back, 2 injectors later and fixed, they were less than a year old too
I'm so glad I found this. I was about to get some injector cleaner for my elderly benz. I don't think i'll bother now!
Not sure what your source is that states the filters were added to protect the debris during the assembly of the engine? My experience with German manufacturers is they had a very high quality and they were not be concerned about debris in their factories. Their concern was rather contamination in the gasoline and during engine maintenance. Unless you have Bosch documentation that states removal of these filters is OK, then you a doing a disservice to your viewers.
It stated in the vw service schedules that dealers had in the late 80s early 90s, out of say 10 units I only find one or two that still have these fitted albeit heavily clogged.
Does that book cover Mercedes stuff as well? Is there a book number on it?
Yes, plus there is also a one that specifically covers Mercedes k-jetronic too, if you search bosch K-jetronic it'll come up
@@GreyGooseRestorations not found the mercedes one yet but I got a digital copy of the other one.
@@jasonbirch1182 I have an 85 model SL, with K-jet and yes, the Chinesium brass fuel fitting internal plastic bit swelled up and prevented fuel into inlet for fuel dist. So, I have a lot of PDF's from Mercedes on the r107, plus plugging exhaust ports going into intake to get my 24MPG, good luck!
@@JP-mu3xl 24mpg from a 500sl?
