Fuel senders operate off resistance, higher resistance when there's more fuel in the tank, so you have a short. Check the wiring harness going to the tank and sender under the truck. Maybe it got scraped or rubbed open, or the plug on the top came loose or got crushed if the bed was overloaded, etc. I also had a gauge go crazy once when I had some insulation push up on the harness on the back of the instrument panel, moved the insulator and it returned to normal. Good luck.
