First do a little test. At the fuel tank, there is a brown/tan wire on the sending unit. Take that connector loose, and with the key on, engine off, ground it(use a short piece of wire, or a small screwdriver as a jumper) to the frame. If the fuel gauge goes to "Empty", the wiring, and the gauge itself are good, and your problem is with the sending unit.
If it does
not go to Empty, then you have either a break in the wiring from the sender to the gauge, or there is an issue with the gauge itself.
