Quote: Looks like this is where my leak is. Finally filled the tank and there was gasoline here. Anyone, know the part number by chance? TIA

It’s the fuel filter under the rear bench on left side.
I need to replace it as well because fuel is present on top.

Heres the parts diagram for my 2010 C300 4matic Sport w/PZEV. Non-PZEV is different.











When I was looking around for prices I noticed eEuroparts has some of the lowest prices for the OE parts. Plus the $10 off your first order.

Yeah. Non-PZEV is more expensive.

FYI, I recently got the P0456 code. Checked the gas cap and the CEL still there. I thought the fuel filter leak could also trigger it, so went ahead replace it and the issue was solved.
