[Bill in OKC]

My fix might only be a possibility if the gauge reads half full when the tank is full (and the sending unit is good). IIRC there are a couple of tabs surrounded by insulating pads on the back of the "pod" (there is one pod for the fuel and one for the oil) that unscrew from the back. There are two of these tabs and they have wires soldered to them . One of them rests very close to the metal case when the gauge is assembled. On my car it actually contacted... I'll see if I can get a picture tonight.
