Mercedes-Benz W204 C-Class Fuel Pump Replacement | DIY

In todays video I explained why my Mercedes Benz C300 wasn't starting but it cranked. one of the reasons it's that it could be the fuel pump issue so I changed it. after I put back the new one the car started perfectly.
Also the fuel pump on most cars its the driver side which is located behind the driver side under the back seat, Also the fuel pump did not give me a code or anything. same for my old BMW 335i I had to change the fuel pump it did not give me a fuel pump code or any code related to it.
Hope you enjoyed watching.

I’m sorry I don’t know for sure but since you’re saying it was the left side then I would make an educated guess and say it’s the fuel filter. The gas tank on these cars (and most German cars) is on the right. And if you’re saying it was full of fuel leakage then perhaps your filter is clogged to the point where that happened. So my guess is you’re referring to the fuel filter but again, just a guess.

[@AlGolzari]

I don’t give any videos dislikes but you’re changing the fuel filter, not the fuel pump! I have a 2010 C300 and know these cars very well, at this point. And some people on your comments asked for a part number. Again, this is the filter BUT for anyone reading this, the part number of either the fuel filter or pump depends on whether you have a PZEV or non-PZEV C300. So please check with your VIN if you’re not sure. Most of them are non-PZEV, but my car is a PZEV, so it’s a completely different part. PZEV stands for partial zero emissions vehicle.

I have a 4matic luxury is it pzev

[@MrRjnr]

I have a 2011 PZEV with 80,000 miles; runs great, but need to replace the cracked cover on the fuel pump side; should I replace the filter & pump preventatively?

[@AlGolzari]

@@MrRjnr​​⁠personally, I wouldn’t replace the entire fuel pump or filter prematurely. Especially with only 80k miles for a 2011. My 2010 now has 147k miles. If you can just replace the cracked cover you mentioned, I’d do that. Sorry I’m not sure if you can just buy the cover you mention. The fuel pump on a pzev should be good for 150k miles so you still have a lot of runway left.

[@MrRjnr]

@@AlGolzari Oh OK, yes I can get the cover separately....thanks so much!

[@AlGolzari]

@@MrRjnrin case you don’t already know and need some guidance, watch the video from pelican parts. And sorry I slightly misspoke - the fuel filter is good for 150k miles. But again, same difference - if you only have 80k miles, the fuel pump (and filter) should hopefully still have a lot of life left.

[@AlGolzari]

I’m just adding a second comment because someone asked me a question and I haven’t seen or thought of this video since my very first comment, where I wrote about pzev vs non-pzev. Again, I think he’s trying to change the fuel pump but he’s changing the filter. *Remember on these cars and most German cars the gas tank is on the right, and that’s where the pump is. He’s saying the pump is on the left, which wouldn’t make sense. The left is the filter. The right is the pump, closest to the gas tank. I hope everyone knows left and right side, especially if you drive and enjoy German cars. No need to say driver or passenger side.

Hello, I would like to change the fuel pump in mercedes w204 c220 (OM646811), what about the filter, does it have to be changed at the same time as the pump? or just replace the fuel pump and leave the filter? I have problem car jerks, has a completely different sound and has a high fuel consumption, could it be caused by it? what is the best alternative, thank you.

[@AlGolzari]

@@jurinecko1415I’m not a mechanic and will not even attempt to try and tell you what’s wrong with your car. *However, I will answer your first question. If you are going to replace the fuel pump, yes, I would also replace the fuel filter. But again, let me be clear - you started talking about other issues regarding your car’s performance and I have no input or comment on that.

[@AlGolzari]

@@jurinecko1415the fuel filter is a maintenance item that lasts about 150k miles. So it should be changed by then even if your fuel pump is still working fine. But if your fuel pump is malfunctioning and you need to replace it, yes, I would definitely replace the fuel filter also so you don’t prematurely wear out the new pump.

[@AlGolzari]

@@jurinecko1415I can’t or won’t provide you with mechanical advice but if your fuel pump is still working and you have the problems you have, you may want to check the fuel injectors and the fuel lines from the pump to the injectors, etc. But it looks like you need to go to a mechanic, based on the nature of what you’re asking. It seems, to an extent, you’re guessing. Which is never good.

Did you ever figure out what the u0101 code was ? I have the same code i got it after I tuned my car and I took to Mercedes they said all my stuff looks good but they suggested I change the fuel pump cause the cause would almost stall on me while driving but actually stall when I get to a complete stop after it only happens after driving for like 30 mins

[@ASMRLIVEFEED]

Hey my freind thinks the same about my car. My car cranks but wont start

Is there 2 fuel pumps?

One is a fuel filter while the other is the fuel pump. I beleive what he changed was the fuel filter

Do I need to replace the fuel filter when I change pump?

[@MoDays707]

I didn’t change mine

[@stormrider01]

I would always begin with the fuses. And then the fuel pump.

[@Dnasty1]

Can you smell faint fuel vapor around these when they are sealed or will they completely block the gas vapor?

[@MoDays707]

It completely block it I don’t smell anything just the first 2-4 days I smelled gas cuz it dropped some around the back seat

Do you have a part number or were you got the part? Thanks

What Year ??

[@deruin78]

Same thing happened to me while sitting on the drive-thru, line putout. I used too much pressure to pull it out in the clip would not hold anymore, so I use a zip ties to hold the gas line on the fuel filter, but now I have to change the fuel sensor.

[@MoDays707]

same bro but my fuel sensor is good

[@cbrown9008]

Does the clip lock in place by pushing it in or pulling it out ?

[@leemorrell6399]

what was the part number

[@arturohernandez3872]

Did you're engine light stay on or did it disappear mine didn't.

[@MoDays707]

It stayed on because I had another code to take care of

[@Dnasty1]

Nice vid. Did you ever get any codes about this on your dash?

[@MoDays707]

No I didn’t but after I put the new one in I had to crank the car couple times before it started.

[@Dnasty1]

@@MoDays707 oh. I’m thinking I may have the early signs of this issue. Did it long crank then start before this or you tried to start one day and it wouldn’t start? Also did you change the fuel pump on the right before doing this? Btw I got that Tcm code and it went away after some driving. I think it was because it was at the shop for a while and they probably disconnected the battery.

[@MoDays707]

Sometimes it long crank cuz of that and sometimes it’s something different but for me it just went out of no where and the tcm code went away for me too I believe cuz the battery.

[@dmorales747]

Mine is long cranking but then starting (for now). Did anyone have this then change the pump and it worked? I would like to know if possible before I change it out. Thank you.

[@Dnasty1]

@@dmorales747 i actually changed the pump first even though I suspected the starter the whole time. The dealer put in a defective one that had me long cranking. I finally changed the starter out of pocket and it solved my long crank issue. Dealer then of course reimbursed me and apologized immensely.
