The wires from the tank pump have a plug at the back bumper in the middle , behind the tank. Just unplug this connector. It will also take out the fuel gauge. Use jumper wire to see which wire works the gauge, and connect that one (those) back up.

Just looked, The gray and black wires go to the fuel pump, the purple wire and the black wire with a white stripe go to the fuel gauge.
