    Ever since I took my tank out to repair it, the gas gauge has been acting up. One moment it'll read correctly then another it jumps to over full. Is this a faulty ground wire? Power wire? Something else?

    sounds kinda like the signal wire
    one of mine does that(dual tanks)
    if no signal, the guage goes over to about the 3 oclock position

    What year? If not FI, you only have the black ground, and in all the rigs I've seen, a pink wire for the sender. But if it's red, and is the only wire except the ground coming from the top of the tank, thats going to be it.

    If your reading over the full mark (about 3 o'clock position) then you have an open somewhere. This is normally between the gauge and the sending unit (power side). The ground side is easy to check since it is a ground strap about a foot or so long.
