does the standard w203 use the same sending unit as the 32/55s? seems like it would be a bit overkill for them. i think it is just bad plastic and there will be a lot of them failing soon. All of mine had pin holes you could not see but as soon as the system pressurized it would shoot a nice little stream.
Also found thread with part number.: https://mbworld.org/forums/clk55-amg...-new-plug.html

The part number you referenced (2114400507) is the wire plug. It is a commonly used part for the 211 fuel pump issues.
The C55 fuel pump (209-470-05-94) is used on the CLK500, CLK55, and C55. It is not shared with the C32 or other 203/209 variants.

Hey Feets, I just called the MB dealer near me (Autobahn motors in California) and they gave me a different part # for the pump (2094704494). Is this because it was superseded, or is it a different part? Now I'm not sure which one to order...

Nevermind - Autobahn Motors gave me a part number that doesn't exist! Called them back and the woman at the parts desk was a real sour puss about it, LOL. Not using them again.

She might have tried to give you the left side level sensor. 209-470-04-94.
It is not uncommon for dealerships to be hesitant when giving out numbers because people will use the info and buy it elsewhere. Dealer does the work but gets none of the money.

Okay, thanks. I think I ordered the right part... Does this look correct? https://www.fcpeuro.com/products/mer...mer-2094700494
They offer 2 "pumps", and this is indicated as the *Left* side. Maybe it's incorrectly labeled as a pump and not fuel sending unit? PN#: 209 470 0494

Phew... Thanks for confirming.
I have seals on the way as well, but didn't get the new plug. Will have to expedite that, as well as some exhaust manifold gaskets for my shorty headers that just came in.

I installed the Eurocharged shorty headers on my C55 a few months ago.
You will need to pop the bottom bolt out of the motor mounts and lift the engine a bit to get the headers in. I also removed the steering shaft and small heat shield to gain a bit of access. Mercedes considers the bolt at the bottom of the steering shaft to be a single use part. It's a good idea to throw a new one at the car. 210-990-06-04-64
Expect to have the exhaust studs pull out of the heads. Mine did. We didn't have enough new ones in stock so I clamped the middle of the studs (fat spot with no threads) at an angle in the top corner of a bench vise and spun the nuts off. Quick and easy.

I got the new fuel sending unit in today! Relieved to get this over with, and clear the codes to have an error-free dash. Thanks for the help, everyone. Will be happy to pass this knowledge onto newbies like myself someday.
The entire process took about 2 hours, most of which was spent cleaning and ensuring the new seals fit properly into the caps on both sides. Also, had to fish the tubes and wires through the small gap at the top front of the tank since I pulled the sending unit out without thinking to tie a line to the ends.
The new sending unit did indeed need an adapter for the plug, so thanks for the heads up on that. I ended up buying the adapter plug at the dealership for $14.
All in, this repair cost me about $265, and a few hours of prep and wrenching. Good to know I have a new fuel filter, which should prolong the life of the pump. Also, not being a rolling fire hazard is nice too.
