Other Fuel System Hoses Lines/piping, And Fittings problems of the 2004 Mercedes Benz E500

I purchased my car used at 132000 miles. This was a pre existing condition that dealer didn't mention anything about, because the next day I filled the tank as it was sold to me with less than 1/4 tank, now I know why, I got a very strong odor of gas that filled my garage and smelled inside the car as well. This happens every time I fill the tank. It also sets a check engine light. Dealership I purchased the car from (not a Mercedes Benz dealership) refuses any responsibility for the problem. Check engine light code is "evaporative emission leak detected (small leak)". Also because of the issue my gas light will randomly start blinking and when I accelerate the center display beeps lights up red and said check fuel cap. Fuel cap is fine, I think it's related to the leak.

You can not put gas into the vehicle it is like there is no vent holes or something because it took me 1hour and 20 minutes to put gas in the car because the pump kept cutting off like there was air in the tank. Maybe its a flap or filter problem, whatever it is it is so frustrating trying to put gas in this car.

I have noticed strong gasoline odors emanating from my car after refueling. I purchased a new Mercedes Benz gas cap and installed it. Filled the gas tank and gasoline odor was still very strong. I do not 'top off' when refueling. Researched issue online at benzworld. Org and discovered that the gas odor issue I am experiencing may be related to a problem being seen in numerous Mercedes Benz e-model vehicles. As advised by the other owners having this issue I detached the rear seat cushion from the car and removed the bolts from the circular access panel that covers a portion of the fuel tank on the driver's side of the vehicle. In the depresion on top of the gas tank where numerous electrical wires attach to the fuel pump I found a significant quantity of raw gasoline pooled. This presents a very unsafe situation and I am no longer willing to park the vehicle in my garage due to the potential fire hazard. The pooling of raw gasoline also represents an environmental issue due to the evaporation and creation of toxic fumes. I understand that Mercedes Benz dealers are demanding $2,000. Or more to rectify the problem by removing and replacing the gas tanks in impacted vehicles. I feel that the manufacturer of this defective component should be held responsible to recall it and replace it. I understand that the NHTSA's current investigation action no. For this issue is pe 12001.
