The float in the fuel tank is attached to a rheostat. Basically that is a resister that sends power to the gauge. Based on how much gas is in the tank, a certain amount of power is sent. Chances are it is going bad. The bad part is this. The float assembly is part of the fuel pump assembly, so it isn't a cheap part and the fuel tank needs removed to replace it.
