When the gas tank is filled over 75% there is a strong fuel smell inside and outside the vehicle. If I fill less than 75% there is no problem. I have experimented with fuel levels from full ( not topping off ) down to the 75% and will have the fuel smell. The smell will cease whenever the level drops below the 75%. Leak is coming from fuel pump seal / gas tank. Called multiple dealers and they acknowledged this is common problem.

While driving I started smelling gas, especially when I would have just filled the tank. This smell went on for years, it got odor got stronger and stronger so finally I went and got it diagnosed and my mechanic said that I need replace my fuel pump and showed me the gasoline under the rear seat (rear driver's side) the amount of gas was so great that I called and asked my rep at mercedes if there was indeed a recall on the part and I also told him that my mechanic said that there should have been a recall on it , and still he said no. So I replaced the part on my own. Now I am smelling the fumes again, I take it that it is coming from the other side. I have to ride with my windows down and/or sunroof open to keep from getting the head-aches again. This have been ongoing for years now . I purchased the car in jan. 2008.

Inside of my vehicle began smelling strong gasoline odor presenting a fire hazard. I found severe leaking at seam at top of gas tank under rear seat of my vehicle & was required to replace gas tank assembly, fuel pump sensor, fuel pump & seals at cost of $2,014.00. I was told that a class action suit against mercedes benz involving year 2003 & later 320e autos for this issue was in progress in atlanta, ga. However florida cars (owners) were excluded on a technicality!!. This danger exists on all cars, wherever located and should be immediately corrected by mercedes. The danger of explosion and death is imminent in any of these autos. Mercedes is and has been aware of this problem for quite some time as was brought out in the class action suit and under our transportation safety rules should have recalled the autos years ago. This is a national problem, and florida auto owners should be properly compensated for their loss as should be any other owners where ever located. Your advise and assistance in this matter will be greatly appreciated..

I own a 2004 e320 with only 44,652 miles. After every fill up strong order of gas from left side near back seat area also check engine light will always comes on. I took car to a mb mechanic trained by mb he removed the rear seat and left fuel sending unit cover , found a huge puddle of gas on and round gas tank pump area. I was told the pump seal was no good, I had the pump and seal replaced, filled tank again with the same result. Finally, last friday, with the seat and sending unit cover off we filled the tank and drove the two miles back to the mechanic shop, when we arrived the whole area around the pump was full of fuel, upon inspection one could see the fuel running from the top of the fuel tank and puddle around base of the fuel pump. We video the fuel running from top of the fuel tank. Contacted local mb dealer where I purchased the vehicle but was told there is no warranty on vehicle. The dealer will inspect and repair the vehicle but the expense will be on me. I don't allow anyone in my family to drive this car because of this problem. This is very dangerous situation that needs to be address.
