New to the forum here, also to fords(die hard chevy guy, but im pretty pleased with this f150 so far , and I think my new truck will also be a f150).Question is my 1985 f150 has issues with the gauges, the tach will randomly work, none of the others work, but my gas gauge goes past empty when I gas up, then other times it will go from e to f only on $10 of gas.Im thinking ground issues, maybe sender? If it helps its dual tanks but only rear tank is hooked up. thanks guys
