Other Fuel System Hoses Lines/piping, And Fittings problems of the 2005 Mercedes Benz E320

Tl- the contact owns a 2005 Mercedes Benz E320. The contact stated that there were strong fumes coming from the gas tank each time the vehicle had been driven. The contact stated that on a hill the gas gage does not show the correct reading. As a safety percaution the contact had put only a half tank of gas to ensure the gas would not overflow or the strong odor would not emmit from the gas tank. The vehicle was taken to an authorized dealer who diagnosed that the fuel tank cap had leaked and the left and right gas tanks had needed to be replaced. The vehicle was to be inspected, diagnosed and repaired. The manufacturer was notified of the failure and the contact was not included in NHTSA action number: ea13003 (fuel system, gasoline). The approximate failure mileage was 120,000. Dyd.

My car remits strong gasoline odor each time that I refuel my tank. When I noticed this smell I thought it had to do with the gas cap. I took my car in to be inspected by a local mercedes dealership and was told my fuel tank is leaking and needed to be replaced. My car had about 45000 miles on it when I first noticed the smell. A car with that low of mileage should not be experiencing a fuel tank leak. I am serious concerned about my car catching fire and exploding. Please help.
