This tutorial series is absolute gold! Thanks. Wish I was confident enough to try all this. I was fooled into buying a 1987 Audi 80 1.8S b3 66kw with what I believe is the same k-jetronik as yours... Its not running well, not starting well, lacking acceleration, and idling all over the place. I live in Bosnia and mechanics here don't want to touch it even though the body and interior is nearly immaculate. Thanks for making this series so clear and concise and easy to follow.
I am about to install new injectors on my 380sl of 1983, and your video has been extremely helpful to understand way is important to check the play of the injector's seals. Thank you!
I would be interested in a video that explains the KE-Jetronic fuel accumulator. I can't really remember if you did one in the past or not? The different types that are out there, what happens if it fails and what maybe the consequences for the fuel delivery system when it's taken out from the equation. I will say from a personal experience that the car will work without a fuel accumulator however for the long run it will start ruining other parts in the fuel system.
For funsies, start with this video by Kent. It's a diaphragm and a big spring! CIS FID Fuel Accumulator Opened Up: You Won't Believe What's Inside! ua-cam.com/video/mD2UrQSWsxI/v-deo.html
Also, start at the 8 minute mark of Kent's video, where he starts discussing accumulators: Mercedes Gas Fuel Injection Delivery Systems 1959 to 1991+ Options for Repair or Replacement ua-cam.com/video/OeOy-y7JCc4/v-deo.html
The basics of "why" for the fuel pressure accumulator: it keeps the fuel in your injection system under pressure, and this is good for hot restarts. The increased pressure raises the boiling point. Early Bosch K/CIS (pre "-E") cars, you could drive them, get them hot, park them, then come back later and have trouble getting them started because the gasoline had turned into vapor inside the fuel lines. Known as "vapor lock." (Also a problem for suction fuel pumps on carburetted cars, etc.) Early CIS cars had smaller accumulators, then had new, bigger ones retrofitted to fix that problem, new cars got bigger ones. Kent in the second video I linked, I believe he said they got smaller again when MBz went to the two pump concept. Fuel pumps running create pressurized gas which goes into a chamber in the pressure accumulator, pushes against a diaphragm seal, and then, provided the seal is not old and dying, goes nowhere. The diaphragm moves against a sturdy spring and now, even if the engine is shut off, that spring pushing against the diaphragm creates pressure throughout the system. (Uh... unless some of your injectors are dribbling! This all assumes no leaks upstream.) I may have solved a hot restart problem on mine recently with the replacement of the accumulator. Or, I've got two to five other problems and that wasn't it, and am still on the diagnostic hunt! You know.... For now, I've got good starting, cold and hot.
Would post a video or a picture about the vacuum sistem of this engine? 110, please!!!!! Like we're it goes tubes from warmer to the warming valve and distributor with 2 diaphragm. Thanks a lot
Kent, have you ever used Hoppes 9 gun barrel cleaner to soak and clean injectors? I know the FAA recommends it for some recip aviation engines. I have had success with it myself on these KE injectors.
That boat is a blast …… only thing is I would feel like I was ripping around in a race car with no brakes. Please be careful…….. maybe a helmet to protect all those years of valuable knowledge 😅
What a way to get your mojo back.
Watching old merc videos is what brings back my mojo.
A mojoception we have here.
Thanks for the support.. :-)

A great idea to have some fun when working on your Merc. Great video.
Kent,it’s either your boat or the Fine Untertürkheimer Lemberger mit Trollinger 🍷………,
👍🏻👍🏻👍🏻
Your buddy from Kansas
That is my boat and it is a rush.... In places I am running in 2 to 3 inches of water...
Great tutorial I’m going to tackle mine many thanks 👍
Wonderful explain about it. Thanks a lot.

Hi Alex, I am familiar with the cleaner but have never tried it on injectors. I will give is a shot. Thanks for the tip. Kent
An Ultrasonic bath can help to clean them imho
It's pretty impressive you still have a full head of hair, Kent. 😉
You didn't look close enough. :-). Should I turn myself in to the hair police?

Are you not King now? 😁
It’s time for KE jetronic videos
Great information. 👍
The opening and ending scenes in the boat----what if a few hungry mosasaurs suddenly popped up? Fast enough to outdistance them? 🙂
My dads 190e has been acting up on cold startup. Im trying to figure out the issue
look at the ignition system, may want to get one of these if there is an issue, look up for 123ignition
I'm looking to buy this kit! (injector, seals, rubbers and silicone caps) Please, make it available asap :) Regards from Uruguay.

Nice boat, too bad you couldn't fit a Mecedes engine in there. 😬
