Fuel tank sender issues
You need to actually do some "diagnosis." Take your multimeter at the tank and stab one probe HARD into the sender flange---not the tank--and the sender wire terminal on the sender, measure the resistance. Depending on how full the tank "you judge it to be" will be the resistance. "Report back." Hard to say, you may have stuck it when welding and jostling around, etc.
The sender resistances for empty, half, and full are in yellow
