Hi kennyb28, there is no damage or dents to the gas tank or rear of the vehicle, I've tried backing it out some, it will still click off unless you go slowly.
It sounds like you have two problems.
1- Bad fuel level sending unit.
2- plugged vent line on the fuel vent hose. (its the small one that runs next to the large fuel filler hose.
***WARNING***
WARNING: The fuel system is under constant fuel pressure even with the engine off. This pressure must be released before servicing fuel tank.
You have to drop the fuel tank to do this so its recommended you replace the entire fuel pump module whe you do this.
The fuel gauge sending unit (fuel level sensor) and float assembly is located on the side of fuel pump module. The fuel pump module is located on top of fuel tank.REMOVAL
