Had a recent issue with the E350 that surprised me, so I wanted to share. Obviously the issues related to fuel leaks on w211's are well known and documented, but I just went through a similar issue on my w212. Heavy fuel smell outside the car, especially after fill up. Brought it to my indie and sure enough the sending unit/pump assembly in the top of the tank had cracked and fuel was pooling. Hadn't really seen/read anything about this type of issue on the newer models.
Pretty disappointing, as you would think MB would have made it a priority to not repeat the same issue as past models. On top of that, I am literally 6 weeks and 500 miles outside of factory warranty...

I would immediately pick up the phone and call MBUSA and ask for a goodwill repair. You might also want to report your problem to NHTSA at safercar.gov
@ CEB - think MBUSA would still consider doing something even if i've already paid to have the issue resolved on my own by my indie? guess it doesn't hurt to try eh...

I would certainly try. Being so close to warranty should be something they'd want to fix - especially since it is a safety issue.
However, the fact that it was corrected by an indie might complicate matters but what does asking cost? Often they'll split costs too.
Call your indie ASAP and see if they still have the old part. The manufacturer may want it if it is still available.
As an aside and not to make you feel bad - but as advice to others - the MB dealer might have actually done the repair gratis had you taken it there. Most would call MB without you asking and try to work a deal.
In hindsight I definitely should have, but my line of thinking was well it's out of warranty, I'm SOL better take it to my guy....
I called MBUSA, lady said it may be an issue since I already took it and had it fixed on my own, but she's going to try and get someone to resolve this. One good thing is that my indie got the parts from the dealer, so even if my angle with MB is to just reimburse me for the parts, that would make me feel a whole lot better.

Isn't it funny how hindsight is always 20/20?
Follow Konigstiger's advice (whatever it is) - he always has good advice.
For what it's worth, my 211 started leaking fuel also, and the car probably had 85K miles on it at the time. Took it to a local MB dealer and while talking to the SA about it the SM happened to walk by and over heard part of the conversation. He interjected and said, basically, "say no more, Sir, we will replace the entire fuel system at zero cost to you".
Hi Folks,
My 2012 E350 (W212) has a fuel leak at the point where the fuel line connects with the top of the unit/pump assembly at the top of the tank, underneath the driver side rear seat.
I started to take it all apart but was unable to figure out how to disconnect the fuel line from the white plastic pump unit.
See attached photo.
Questions:
how do you disconnect the fuel line from the white plastic unit cover?
How difficult is it to replace the fuel line/connector?
That blue fuel hose BLACK connector is a PUSH-TO-RELEASE type at the base to release, kind hidden from view.
So ur o-ring is probably leaky.
There is 5 BAR of pressure in that blue fuel hose, becareful. See the link and study it well. Ask more when you need it yah.
Battery disconnect is best-safest and a MUST to prevent fuel pump priming itself.
