I started to smell fuel leak so I checked and a little fuel was coming out from the fuel line in the engine compartment.
See red arrow in the picture below. I noticed there is no clamp on the black rubber. It's as if it's compressed in to the metal fuel line. What I did is I installed a clamp and the leak stopped.
Will this be enough or should I buy the whole fuel line? If yes anyone have a part number?
Hose between the fuel pump and fuel filter A208 476 2126
Fuel tank to inlet of fuel pump A202 470 2475
Fuel filter to main line to engine A230 476 8726 (230mm, may be sold by meter)
Fuel filter return line to tank A208 476 1426
Make sure that if you aren't using the genuine "click" clamps that you are using "EFI' hose clamps that have a solid band around the hose. see pic, don't you a hose clamp that looks like the one on the right.
I would also suggest checking the rubber return hose that feeds into the Left hand fuel sender, I have seen a few of these leak.
I would also check the breather hose leading up to the filler neck (remove RHR wheel and inner wheel arch cover. I have had these perish on both of my W202's, whilst they will only leak liquid fuel with a very full tank, they will make you loose fuel without knowing where it went on really hot days.
Mickey thanks for the info.
The part numbers don' show what in looking for. This A230 476 8726 just shows a black rubber hose. Is that all I Need?
if that's the case I will have to cut the old hose on both ends. Something I didn't want to do. I was hoping to fund the whole part. The metal part that goes to the fuel injector line. And than the rubber hose and the metal part that the picture shows. All one part, they don' sell this in ONE piece?
but the photo you posted at the first post for fuel rail hose, isn't..?!!?
-;ZAYED;-
That' correct, fuel hose I need is for fuel rail in the engine compartment. But all hoses I find are for fuel pump to fuel tank as you said. So confusing...
The EPC shows 202 470 23 75 - Fuel Hose from Feed Line to Engine, for my son's '99 C43. The hose has hard fittings at both ends, no clamps. I personally would not drive your car considering where the leak is. The steel tube of the hose where your leak is has a "barbed" section where the hose connects (grooves to prevent the hose slipping off). The sleeve next to the leak clamps the hose onto the barded section. It's hard to tell how far the barbed section goes past the sleeve, so clamping it at the leak may be just barely holding on. A local dealer should be able to get the correct part and there are several M-B dealers with online parts operations that should be able to help. I've used these folks on occasion, https://www.mercedespartscenter.com/...?siteid=215720
Thanks Vince, but 202 470 23 75 keeps coming out as part for fuel tank to fuel pump hose. The one I need is threaded to the fuel rail which feeds the fuel injectors. The other end is threaded to a line which I'm guessing goes to fuel pump. This end is showing in the picture I posted.
Between these metal threads is a black rubber hose. Bottom end is hooked up to the metal part with a pressure clamp. The top part to the other metal but with no clamp.
I'm looking for this whole piece which is like 12 inches long.
I don't know where you are finding that that P/N is from the fuel tank to fuel pump. The EPC is the Mercedes parts system. The description is a quote from that system. The drawing in the EPC shoes a part with hard fittings at both ends. The EPC shows 202 470 24 75 for the hose from the fuel tank to the fuel pump. I know exactly what hose you are looking for. I don't understand what sources are causing the confusion. Try calling a dealer. I find they are often the best source.
I have no doubt the P/N is correct - both ZAYED and myself have confirmed it. I'll have the dealer confirm it again. But my sense is you are frustrated trying to google the part and you don't want to try the dealer link I provided. The number comes up at about $46 USD. Other alternatives:
1) Take your hose to a hose shop that sells and services hydraulic hose. They can make one up - or
2) Take your to a local race shop or race track that has a parts shop the supplies parts to the teams running the track. I run at VIR (Virginia International Raceway) and they can make up hoses on site. One of our PCA instructors had a leaking fuel hose and I was able to make up a new one for him from supplies I got at the track shop - or
3) Another dealer link: https://www.genuinemercedesparts.com...ose-2024702375
I'll reply tomorrow with P/N confirmation. By the way - what is your location? US? Or?

I did check the link you provided. They don't show a picture of it so I don't want to get it. If its not the whole thing and just a hose I don't want it. My dealer is far from me but will have to drive out there. And I know the part number is correct but I just want to see what I'm buying. Thanks for all the help.
Understand. But I would call your dealer before driving a long way if you want to see the part first. That hose is not a fast moving part and very few dealers will stock it. The online guys will likely order it from one of the M-B parts depots - they get the part overnight in most cases then ship. Look for all the P/Ns ZAYED provided. You may have better luck finding a photo or actual part. I'll check my dealer tomorrow. They have a pretty good stock, but no promises.
Below 2 pdf files I've pulled from the EPC containing in one the image of the fuel lines and in the other the parts list. Hope that helps you identifying and/or confirming the parts needed.
My local dealer confirmed that the correct P/N is 202 470 23 75. He did not have one in stock so I could take a photo. BTW, you are looking for Item #59 in the drawing. There is now conformation from multiple sources that should give you some confidence in ordering one from your local dealer or one of the online sources provided. Hope this helps.

Thank you very much Vince and everyone. Really appreciate the help.
