All K and KE Jetronics from Bosch has a very fine screen filter attached to the inlet side of the fuel distributor. This serves as a final filter before the fuel enters to the most sensitive parts of the fuel system, such as the plunger and barrel, metering slits, and fuel injectors to name a few. A lot of technician overlook this important screen filter because they thought its just a simple fuel inlet line connector. Thanks for showing this part on your video. Well done! All the best!
I have a 1987 vw passat cli, 5 cylinder with K jetronic injection and i've struggled for month with the fuel pressure, i watch this video and just decided to check the filter of that very same screw and low and behold the fuel pump stopped laboring and the car could rev up again. Thanks MMWA for posting this very important video.
One thing I am thankful I learned from you working on my 140 is: knock a nut loose, put wrench aside, use your hand. Its like therapy.
A good friend is a VW master tech, and he always tell the story how this filter was supposed to be removed on the VW CIS cars at the first oil change, but rarely was and would lead to running problems down the road.
compu85 interesting, so its also for cleaning out any residue during the running in process. I wonder what the usual replacement period is, if any.
Thanks for you video. The mercedes dealership and workshop did not know about it. Xentry and WIS do not mention that is a filter inside these fittings. Finally I got the part changed and now there is much better acceleration at lower rpms. Cheap an simple job with great effect
what is the part called so i can translate it and see in my country to buy it?

Where can we buy it in Serbia ako znaš?
Thanks so much for this! The Mercedes part number seems to be A0000745786 (at least it is on my M102)
takk:)
Great Video. Do you have the original Mercedes part number for this?
I was just pointed to this video by one of my channels viewers as Im trying to get a barn find W123 started, I had no idea there was a second filter it the fuel injector end, thanks!
Neither did I till a good friend showed me
@@MMWA-DAVE I got mine out today, totally gunked up so I cant even blow through it! Where did you buy your replacement? my local motor factors had never seen one and the internet is drawing a blank! Thanks
@@furiousdriving almost everything is on eBay, I got these delivered from Latvia. They are also available at the dealer at ridiculous mark up. The part number is visible on the bag in the video.
@@MMWA-DAVE Cant believe I missed that number on the bag! I was looking on ebay but just found fuel distributor rebuild kits without it. Currently the old one is in a shot glass soaking in my wifes nail varnish remover as I was getting desperate!
furiousdriving fortunately they are pretty cheap from Latvia, only problem is the postage is always as slow as hell from there. Takes about 1 month to me in Australia.
It wasn't clear to me what problem or symptom you were trying to cure by replacing the filter. Maybe I misunderstand. Any comment on that? Thanks for your good vids. I have a 300CE-24 and it's almost running like new at 1/2 million Kms.
Simple and very effective maintenance. Thanks for the video!!
hello.what are the signs that it is not working? my c124 300ce cold engine does not start if you do not press the gas pedal.could this be related?
What's the part number for replacement inlet filter ? Can't seem to locate it on searches....hmmm. Maybe just clean ?
Its on the packet in the video X-ref is refering to MB part number. Which is 0000746086 for this particular version.
Where and how did you find this part? I couldn't manage to find it for my w124 2.3e m102 engine.
Greetings from Serbia
Ivica Jovanovic Hi, try to source this: partsfinder.bilsteingroup.com/sr/article/febi/19947? It is situated at the back of the fuel distributor right at the fuel feed line/hose coming from the tank.
@@ringokeller81 Thanks, I really appreciate it!
I just found mine on my w124 M102, there was no filter on it...it was open..any idea why.
@@redpig1120 Because some fool thought it would be better if there was no filter there. In the meantime I managed to find and to replace this part.
@@mercedeske actually my mistake, I was looking at the front pipe, it’s on the back...I found it, it has the mesh😂😂😂...although I will replace as its dirty..thank you.
The information I got from this site an the help was right on the money of what was wrong the car is fixed an running perfect 10 stars
James Greer heh, what i started out doing was blogging my progress with my blue/black 124. I’m glad if anything I have shared has helped fellow older mb enthusiasts like myself.
nope , i cleaned mine after rebuilding it , great vids more Mercedes 190e if poss , thanks
I thought mine was clean too when I rebuilt my fuel distributor.
turns out that even though i rebuilt the fuel distro above the MAF , i was still getting loads of fuel dumped into the engine , changed it out with another Distro and wow ran perfect first turn of the key, seams an injector inside has gone and i cant find the replacment jetss , shame i spent £60 on the kit and now got a dead fuel distro ! but atleast its running as it should
It might be for entertainment, but I'm about to go do it rat(sic) now....;-)
At 2.42 in your video you take off a pipe iv drained my fuel tank of old petrol my question is if I took off the pipe you have just did could I drain the remaining old fuel in the line under the power of the car ?
in my opinion the best way to drain the tank is to disconnect the large suction hose that runs between the bottom of the tank and the first fuel pump from the pump side. Have a suitable sized bucket ready because the fuel comes out very fast. While the tank is empty you can install a new screen filter in the tank too. I have to do all this in my red w124 and will make a video next year.
Sadly this will probably be one of the last jobs I do on this car. I will be looking to buy something else later this year if the opportunity arrises. I want to get more involved with OBD2 era benzes as electronics and diagnostics is where my interests really are. I only ever got involved with mechanical repairs and maintenance as a young man as a necessity to make every dollar stretch as far as possible, as I age further and money is no longer the main concern I find this sort of work less and less interesting.
This car I also never intended to buy, it came to me as a rescue mission. The previous owner contacted me through a work colleague and said he had a benz too good to send to scrap which needed a bit of work. Once i saw the picture of it and the condition it was in, it was love at first sight. I have probably spent near 10 thousand dollars on this car for my amusement and in reality it is only worth 3 - 5 If i'm lucky. I will probably cover it up and just forget about it when the new car comes along.
Nothing drives better than these old benz's. Unless you get a new E class or greater. Forget it.
MMWA what kind of symptoms does a car have when that filter is clogged and what is the benefit of changing it out to a new one, I'm a curious one in nature, so this is just for my curiosity and would appreciate you sharing your knowledge
Hi. that is swirling element to assure the fuel flow is as intended. just cleaned with mild mix of fuel and carburetor cleaner. good job anyway, cheers!
Just changed mine after seeing your Video Many Thanks
Does the w201 also have the filter? Would it be the same as w124? Is there a way to clean the filter? It seems pretty simple
Do you have an answer for your question? I got the same problem.
You sure this works on sl300 ?
Where can one find replacement filter elements of this type?
Some comments and explanations would be useful
I know my early videos were crap - I was too scared to talk on video.
After watching this video I have purchased one of these and was surprised to find that the so-called filter is basically a plastic tube?
that doesnt sound right, its the brass fitting at the fuel distributor with an integrated screen filter as shown.
@@MMWA-DAVE well I got around to changing the port today and it was the right part, and it may just be in the head but the engine seems to be ticking over a lot better than it was. What indeed the filter is a tube of plastic.
how is the part called so i can translate it and buy it in my country????
Hi I have the same engine in my coupe, it will not start when cold I managed to start it and was very smooth and run great I have changed one of the fuel pumps ,the plugs ,dis cap would any one know what I can replace ( the cold start temperature sensor ,cold start injector ,the other fuel pump ,the OVP relay, the MAS relay ) I am getting a good spark .I have spent a lot of time and money on painting the car but now it's got to the point were I am very close to towing this car to the scrap yard and calling it a day..My car is a 1993 300 ce coupe . Thank you for any help .
try research on the accumulator and warm up regulator
What do you say, David, is there any improvement as you changed the filter?
Ивица Јовановић the difference could have been imagined. Ultimately a fuel pressure gauge would tell if there was any difference. I do have one too but didn’t think to test at the time. I don’t think this makes a big difference unless the original is severely restricted.
I always have to add fuel to the fuel bowl to get my 300sl started 1991 I change the fuel filter plugs rotor and distributor cap check both fuel pumps seemed fine doesn't seem like fuel is getting to the engine any idea or help from anyone.
wow,now my car has 15hp ,more....
SOLVED!!! my 78 m110 fuel issues.Ccar runs like a clock after this. Used to die and misfire before._The original was severely restricted.
There is no such filter on Audi 100 C3, at least on the RT engine 1989-1990. There is a "thing" looking like the above filter, but I dismounted it and it had no filter in it.
How did you know that little brass colored inlet fitting needed to be replaced ? The old part you took out still looked in good condition
I just changed mine (1990 300CE). Thank you for showing us this part. Interesting fact is that my local Mercedes Service claimed no such filter exists in this engine...
It certainly exists and I can tell that in case of my car it hasn’t been replaced since new (30 years). My first observation was that the old one was definitely not as freely letting the air go through it and the new one.
5 mins job, very satisfying, I made myself believe that the engine runs happier too 😋
Thanks for the info, where can you purchase one of these filters?
@@daithibenz3767
eBay- search by part number showed in the video. There’s a seller in Eastern Europe who sends them quickly.
is this really a filter??
sure is, its got a cone shaped screen inside the union with very fine holes in it.
This may be the exact reason my w201 that’s been sitting for several years quit when it gets warm
What kind of rely was that at minute 5, it has some sort of switch on it?
you should have used two wrenches to tighten the coupling.....
Yes, I probably should of I agree.
Thats another job added to the list, thank you, Cheshire UK
Where do you buy this?
William Tan got mine on ebay
Thank you. 👍🏻🏴
what color(type) of coolant are you running?

@@MMWA-DAVE Thanks! ive been wanting to change over from G05 because its so hard to see in the reservoir...
Was that a new filter you fitted or have you just cleaned it?
Read his paragraph above.....jeez
Would you able to share with us where you get all your German parts from? I am in the US and always getting many reproduction from CN. Not against Chinese but the quality come with price we pay for. Thank you in advance!!
lots of one off purchases come from ebay, theres many european sellers with new old stock benz parts not available anywhere else. I also buy from fcp euro some things they have in stock of decent brands. I buy quite a bit locally for service items too
My 190e2.6 has a idle problem I will be starting with the iacv peace and love
Make a video so others can learn too. More information out there the better.
I have 300E in the morning its start nice but after its hot it takes time to start ,what it maybe a problem
@@patrickthabanepeter4938 fuel accumulator
do u know if the 1986 300E has this and if so where do i find a replacement?
As far as i'm aware every K-jet car has it. I got mine on eBay. The part number is on the bag in the video.
MMWA thank u so much for the quick reply. My car hesitates a little I wonder if this could be the reason
You know what, mine has started to as well - ever since I changed the fuel pumps the fuel pressure has increased and now the car runs worse - almost like there is a bit of a vacuum leak. Shifting from R to D sometimes it feels like it wants to stall though it doesn't. It never used to do this before. I did have to adjust the duty cycle after changing pumps too. I will get to the bottom of it sooner or later.
Hi MMWA,
did you find a solution for this problem?
I hope you did, thanks.
MMWA Hi thank you for your video’s they are very helpfull.
Have you found the solution for the R & D idle issues? I have the same car and I experience the same symptoms. Dont know where to start looking...
Thanks for a good job..
no filter inside this part of a kjet golf 1 1983 DX. Check the intake of the WUR
Thanks. I am only familiar with the setups used on the MB’s.
Is this a late m103 engine, never seen such a camshaft cover in w124 before?
its the first generation M104 with KE-jet. Only existed for a few years and was then turned into the 3.2 litre m104 from 1993 onwards. In the USA the engine was used in 2 cars only, the 1990-1992 300CE & 300SL. here and other parts of the world it was available in sedans and estates too and called the 300E-24 etc.
MMWA Ok that 24v engine. Of course. I had the assumption theyd be all motronic/lh-airflow gauge and solenoid injectors. But thanks, now I am a tiny bit more educated again.
there is one version of this engine, enlarged to 3.2 litres still with aluminium intake manifold but no KE-jet used on 1990-92 W140 300SE. it has mas airflow meter and electronic fuel injectors. That engine exists in no other car, perhaps thats where you saw it.
M103 or m104 engine which one
Welche,Syntome hatte der Motor vorher. Und nach den Tausch?mfg
I had several years of problems. The injectors changed, fuel pump changed, fuel filter changed (on each service), turbo rebuilt, turbo return valve rebuilt, turbo pipes checked, spark plugs changed (on each service), WOT valve checked and on more then .6 bar turbo pressure it either failed, or didn't shown any strength. This thing was completely obstructed, and a new one solved it all!!! THANKS!!!!
which car was this with turbo and K-jet?
@@MMWA-DAVE ferrari 208 gtb 1987
@@josbar313131 heh, i never thought a ferrari owner would watch one of my videos, but here we are 😀
Excellent work!
friends, do you know where the w124 gas station relay is?
fuel pump relay?
what was that you removed from behind the battery? and is it necessary?
Hussain Jamal it is the MAS unit, which incorporates the fuel pump relay among other things. The object was to depressurise the fuel system, but in reality it still poured out everywhere anyway. Venting tank pressure makes sure fuel does not continue to flow out of the disconnected supply line, which happens on this car if I don't open the cap before opening fuel system.
@@MMWA-DAVE I onces tried this trick when doing a fuel pressure regulator on my sisters Pontiac Grand Prix. Pulled the relay, the engine stalled a moment later. Unfortunately there was still a lot of pressure in the system and I got a face full of gasoline. I'm glad I was wearing glasses, not contacts that day! Still got a bunch of gas in my eyes... man that hurt!
compu85 heh, fortunately I’ve not experienced this yet. These days i put a cloth around the connection while loosening as I dont like getting fuel everywhere let alone on my hands.
What r the synthoms Thanks
Тема хорошая но понять не могу
А на русском не лзя
Is that car a 300CE? If so, I'd love to know the part number for the fuel pump relay
its 300E-24 which has m104.980 engine. If you are in USA, your 1990 to 1992 300CE used the same engine.
@@MMWA-DAVE Thanks! I learned that the m104.980 doesn't have fuel pump relay, but an MAS--just bought one. If you've done any videos about replacing the ECM on this engine, I'd be grateful if you could direct me to it.
@@matthewsmith8249 yep mas relay performs a combination of functions not limited to fuel pump. Also does AC compressor, heating of the o2 sensor and probably other things i forget about.
@@MMWA-DAVE Hope the OVP and MAS solve my tough start/occasional hesitation issue. (Prob. the ICM though

Thank you!!!
one last inquiry before you retire! what part on a '91 300sel would suddenly create a very loud scraping noise after a rapid acceleration then cause the engine to cut off & not restart several minutes later? I pulled over & popped the hood but couldn't determine the source. RPM's were normal. I've had a crank no start issue for 2 months now with mechanics giving different opinions. Autobahn Auto in Hampton, VA wants me to buy a new engine without first opening it up to see what,if anything, is actually wrong with it. it didn't overheat or lose oil pressure before cutting off. check engine light didn't come on. timing chain is intact. car ran great since buying it from a doctor a year ago. Help! Work and everything else is suffering!
Thanks, Kevin
Retiring ? LOL I'm 36, I wish. is that a w140 300SEL or a w126?
+MMWA young'un! it's a w126. this is what it sounds like when I turn the keyua-cam.com/video/470A4l_1BMk/v-deo.html
thanks a bunch for responding
Beautiful Body i gotta say that definitely does not sound good. Is the motor actually turning? Ie can you see the fan spinning? My guess is the timing chain has let go and caused a catastrophic engine failure. Take off the valve cover to verify.
Beautiful Body if the body and interior is still good id consider sourcing a good used engine and transmission and just swapping them out. Or at least the engine. Im not sure what differences there are on the w124 but there were thousands sold so should be plenty out there. Some swapping of bits between them may be needed to make it fit the 126, im not sure.
+MMWA weather permitting I'll open it up tomorrow. haven't done this before, should I get a gasket first?
i have 1987 Mercedez 190E 4cyl carburetor it crank but it's hard to start
