Fuel gauge is inaccurate and fluctuates when truck is in park or neutral reads between 3/4 and full when driving even if tank is close to empty. Drops to show tank is empty when in park even if full.

I ran over a pice of a tire in the road. The steel belt apparently penetrated the upper side toward the front of the vehicle, of thin plastic fuel tank. There is a shroud between the drive shaft and the tank, but it does not extend to the front end of the tank "its 2 inches too short" and there is no protection for the front or bottem. The tank was barely scratched but was leaking through a pin hole. These tanks should be protected better or made if thicker plactic. A single strand of wire should not cause a hole in the fuel tank. The dealership stated it was not covered under the warranty and sugested I should patch the hole with "jb weld" epoxy as the new tank was $800. 00.
