I did this myself and replaced the fuel pump. Wouldn't work. Read the fine print on the pump instructions and ended up reversing the wires. Lesson learend: connect the pump and test in a bucket of water BEFORE installing. The wires might need to be reversed. Also, there is a black rubber stopper at the end of the fuel pump/gauge sender unit that needs to sit in a cup/bracket inside the bottom of the gas tank. If you don't get it seated properly, you won't be able to tighten the ring around the outside of the tank and get a good seal. Make sure to get the old one out if it has fallen off.
