I need to replace these but cant find any info on them(part numbers and which ones are replaceable)

Ever since i changed my fuel filter the car has been weird on startup. It would hesitate for a second and it feels like i go through fuel twice as fast than i normally would. I have a feeling some of the hoses cracked while i was moving them around trying to get them off and on. First day after i replaced the filter the fuel dripped a bit in the back but i havent seen it after so i left it alone

If someone could point me towards a diagram or part numbers to all replaceable hoses down there i would really appreciate it

did your new filter come with new copper o rings?

mangupe, citaj very carefully!
you have to replace the short L-shaped hose, this one's a real M-F!
this hose brittles in the angled corner, your car will leak a lot.
capisch fraer!

Nope didnt come with anything

Any of you guys replace this part on your car? Whats the part number?

Ausmbtech

For a C43 and not a C36


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.

Thanks so much for taking your time to provide this info

I went to the dealer yesterday and ordered the hose that connects the pump and the filter. Ill start with that and see how it goes.


Ill save the info you provided

ausmbtech, where does one source those "EFI hose clamps"? Never seen those before?

Ausmbtech

The clamp on the left is usually only an OEM fitment because they are designed to clamp a particular size hose rather than a range of sizes. Basically as long as it has a smooth inner surface rather than the groove in the band contacting the hose like the one on the right they're fine to use.

doing my fuel filter and hoses. which is the better fuel filter, bosch or mahle?

cm60k

Both will work fine, but prefer to go with "Mahle"..

;ZAYED;

mickey13

ordered mahle fuel, also new bosch sparks, bosch wires and 2 mahle oil filters from FCP with lifetime warranty on all parts. they have a christmas sale now so their prices are close to autohauz but you also get the free lifetime replacement


do you think ngk sparks are so much better? i just went oem but can probably change order.

cm60k

Excellent,

Sure, NGK is so great, MB & many companies have an agreement with NGK,,

i'm using NGK's since around (8) years, with fully satisfied..

I'm more a Bosch man for my plugs, even if I had NGK's on the engine the first time I got around changing the plugs 4 years ago. During the winter I'll be installing Bosch Double Platinum plugs #FR8DPP33X, together with some other things...

mickey13

i stuck with OE. i think it was #FR8DPP33+
doesnt really matter, i have lifetime warranty on the plugs so even if they only last as many miles as i guess
