With a full tank of gas, gas leaked out of the top of the fuel tank where the fuel sender/filter is located. The fuel wicked up the foam wrapped around the signal/ power wires, came between the access panel screwed to the floor and the floor. This is the floor directly under the rear passenger seat. The fuel soaked into the insulation below the rear passenger seat and the foam seat. This continues to occur at all times until the fuel level reaches approximately 3/4 of a tank.

Reference the federal safety agency action# pe12001 there is a fuel leak at one or both of the fuel sending units and at one or both of the fuel pumps located in the gas tank of this car. When filling the gas tank to full, gas leaks and produces a very strong gasoline smell inside and around the exterior of the car. I have removed the rear seat to gain access to the units and I have observed standing gasoline on the top surface of the sending unit seals. There are electrical connections inside of these units and they appear to have been shorting due to the leak. This is potentially a very hazardous, life threatening condition.

I filled the car with fuel and drove it home and parked it in the garage. The next morning when I went into the garage there was a very strong odor of gasoline fumes. The fumes were not in the passenger compartment, but rather, outside the car. After driving the car for a while and using about 1/8th tank of gasoline, the odor was no longer present. The repair shop has determine that the fuel sending unit must be replaced. I think mercedes did a recall for this problem earlier.

Filled my just purchased 2003 e55 amg with gasoline on 10/30/14 and drove straight home. After a few minutes my brother told me the garage had a strong gasoline smell. Drove to work the next morning and noticed the smell was extremely strong in the car and left windows down to ventilate. Drove home with windows down and still noticed smell that seemed to be coming from back seat of car. Entered car and "gasoline smell" into internet search to find there is a large scale issue, investigation, and lawsuit. When picking the car up from dealer I noticed the entire rear seat bottom was not attached. Thought it may have been due to an inspection. However, it turns out that the access panel for the fuel sending unit is directly under the seat. After learning this I removed the rear seat to find gasoline on the access panel. Removed the panel to find a puddle of gasoline on top of the tank around the sending unit. Immediately called the dealer and they said to park the car and a tow truck would deliver it to them. Then the dealer called and provided a number for me to call mercedes benz USA to arrange a tow truck. Mercedes arranged the tow truck and hauled the just purchased car back to dealer. Dealer is supposed to be checking it on monday 11/3/14 to let me know the status.

I got home from the store smelt gas thought nothing of it at first. The next day I was driving my vehicle with the windows down got a big smell of fuel, that got me thinking. Later that day when I got home I started smelling around my vehicle. Opened trunk smelt gas. Then I smelt both rear wheel wells and smelled a strong fuel odor on the drive side rear wheel. Further investigation I got under the vehicle to check it out. I could see fuel running down the side of my fuel tank. So I removed my rear seat and the cap under the seat to see the fuel sending unit from above. When I removed that there was a stream of fuel shooting out of my sending unit. I did some research on this claim and I found out its a common occurrence. That there was a previous recall and that didn't do the fix. I have a picture of the sending unit shooting the spray of fuel but there is no area to upload it on here. I would like to know what is going with this. Thank you.

Very strong smell of gasoline inside and outside the vehicle. Regarding the interior, it was determined that there was a leaking seal at the fuel sender unit. The seal at the fuel sender unit was replaced in march 2010. This problem recurred in late 2013. In march 2014 the fuel pump assembly, fuel pump lock ring and fuel sender seal were all replaced with new parts. The problem has re-appeared again. Regarding the exterior smell it was determined that there is a fuel leak at the fuel tank vent area. This was initially manageable by keeping the fuel level below 3/4 full. In the last couple months this problem exists at any fuel level. This overwhelming fuel smell will completely envelop the entire garage within 15 -20 minutes and possesses an extreme health risk and potential for an accident to happen. The level of exterior odor now is so high that it penetrates into the interior of the vehicle, whether the vehicle is standing still, in motion and with the engine on or off. From the research I have done this exact same problem is common to this model mercedes benz and has been documented for a number of years. I have not received any notification or communication from mercedes benz at any time regarding this issue. This is unacceptable!

The fuel sending units under the back seat were leaking fuel directly into the passenger compartment. The floor mats were soaked with gasoline and the foam insulation under the rear seat, and the foam in the rear seat soaked up gasoline from the leaking fuel sending units. The sending units were replaced by the mercedes dealer at a high cost (a little over four thousand dollars). Over a year later, with lots of baking soda, odor killers, and leaving the seat out of the car with a fan on it for two weeks, the odor is still strong in the car. Probably the only real fix would be to replace the rear seat, the carpeting on the floor, the mats, and the insulation under the rear seat. The cost to do so would be high. Mercedes should recall these cars and own up to their problem. I have no doubt that any spark near the floor or bottom of the rear seat would have caused a major fire. Luckily, that did not happen.
