long story short I need a new fuel pump in my 03 e55.

signs of heat/dark colored plastic inside fuel pump

already made a few threads and ordered fcpeuro fuel pump kit for $1k https://www.fcpeuro.com/products/mercedes-fuel-pump-replacement-kit-genuine-mercedes-2714700000

bbirdwell has been more than helpful I owe him a beer

but I still want to confirm something with EPC.

my vin is WDBUF76J63A365904

is the fcpeuro kit ok? the shop that has the kit and my car is still acting like they need another harness!! doesn't the kit include everything? I think they could be running into a PZEV/non pzev issue??

what fuel sender and pump does the official MB system say I need...

I know I have the right pump I am more concerned about the driver side assembly

If you post a picture of the top of your sender unit you will see an extra pressure sensor.... or lack of one.

Continued via PM but here is the thread where it was discussed that non PZEV cars can use the PZEV sender unit for anyone else needing to know.

thank you man.

everything appears to be up and running a few days later now...

to clarify something already discussed on the forum - yes I'm pretty sure my early early 03 e55 was non pzev and we just put in the newest PZEV fuel sender and pump

my private Benz shop (who never had to do these since my 03 is the first car out of warranty) was very confused by the one of the small hoses not having a home, the Y-setup deleted, and the pressure sensor just sits there, but it all works

will update in 100+ miles but I'm hopeful this chapter is over atleast until the next 60k interval when I get to do it all over again.

next up will be finding a shop who can change the the relays as some people have done
