My fuel gage is running wild. It was reading 1/2 tank and when I turned the engine off and restarted the car it was now reading 1/4 tank. I went and filled the tank up and it took 14 gallons. It is the second time it has given me a false reading. With my luck I will take it to the dealer and I know it will not do it then. Any ideas what can be wrong. Thanks and Happy New Year. My corvette is a 2001 C5 Coupe.
