Tank Filler Pipe And Cap problems of the 2006 Mercedes Benz E55

Summary: both fuel sending units leaking from the top of the fuel tank. Fuel was puddling under the rear seats and was dripping on to the ground. My 6 year old son got in the car this morning and complained that it smelled like gas. This a major safety issue as well as an environmental issue. What would happen if the leaking fuel came in contact with a hot exhause pipe? a recall was issued for this same problem in 2008, however, the recall did not resolve the problem, it only delays it until you are out of warranty and are forced to pay out of pocket for a costly repair.
