Tank Mounting problems of the 1998 Dodge Avenger

When filling a empty gas tank, I can get about $2. 00 of gas in before gas splash back occurs. This causes large amounts of gas to pour onto the ground and on my shoes and clothes. I have tried 6 different gas stations and each gas station does the same thing. So its not the pumps. It takes in upwards to 10 minutes just to pump $7. 00 in gas into the vehicle while still splashing gas on the ground. Im told this has to do with faulty rollover protection valves sticking. When filling up via gas can this problem does not present itself. Its just when filling up via gas pumps. This is very dangerous to not only the car and any person/sputting gas into the car. But also to the environment.
