Fuel Gauge Pegged Full

When the ignition is off, it reads zero, but once on, it pegs above full. Stays that way and doesn't bounce. I'm sure that it's not the gauge

If there's a loose wire, would it peg high or low?

I have to drop the fuel tank to replace the rear crossmember and just wondering if I need to replace the fuel pump at the same time.

Sounds like you sending wire might be ground? I had an issue like this once. Is this a new issue or existing? I think it's a wiring issue, but I could be wrong.

When this happened to mine I found upon removal that the float had become wedged at the top of the tank. What had caused this was I came down a steep grade & the hitch/bumper hit solid on a rock. My fuel level had been at about 3/4 tank when this happened so the float was already pretty high in the tank. So i guess the sudden shift in the fuel bounced the float upward & became lodged at the top of the tank.
