Fuel Pump problems of the 2006 Mercedes Benz E55

Strong gas smell inside vehicle after fill up, or while sitting on an incline. Remove acess covers to fuel pump and fuel sending unit, puddled gas observed on top of tank.

Please reference existing NHTSA complaint #pe12001. My 2006 mercedes E55 has raw fuel puddling under the rear seat area behind the driver's seat. There appears to be a leak from the housing or tank itself in this area. The fuel leak is substantial and the vapors from this leak are overwhelming inside the car. I have taken numerous detailed photographs of this leak. I also have a video clip that appears to capture a hissing sound of pressurization inside the tank forcing fuel vapor into the interior of the car. I would be happy to share any of this information with you to help with your investigation. My understanding is that you have already received several dozen complaints about this exact problem from other mercedes E55 owners, and perhaps from other mercedes models that use the same gas tank / sender units. Due to the amount of fuel that is puddling up in the back of my car, I am afraid to drive it and the raw fuel smell is giving me a headache even when I keep the windows rolled all the way down. I would appreciate your help in applying pressure on mbusa to provide a valid and complete fix for this issue.

Reference NHTSA action # pe12001. After refueling car, interior would have an overwhelming smell of gasoline after leaving it parked. Investigation revealed fuel pooled up underneath rear passenger seat and required replacement of fuel pump.

After filling up the car with gas, it smells of gas fumes from the left rear wheel well. Happens every time I attempt to fill the tank. I've been filling gas tank to only 3/4 tank to reduce the gas fumes emanating from the car after gas fillups. Maybe poor seal with fuel pump and gas tank itself. Car was looked at in a previous recall campaign, but problem persists, and based on online reports, is a very common issue.
