Fuel gauge goes right to full when the key is turned on. Had the gauge assembly out of the truck very recently and refaced three of the gauges and installed a new (NOS) temp. gauge. Everything working fine except the fuel gauge, worked great before the new gauge facings were applied. Carefully marked the wiring prior to taking the gauge/speedometer assembly out of the dash so the install would go smoothly. Took the time to double check everything when it went back together, all wires went back to the same spot where they were taken from. I'm sure this kind of problem was discussed back in the archives someplace, but if anyone has a thought on it, please share.
Thanks, Tom
