Good stuff from LonnieC. My 2 cents: Run separate "test" wires. One from the sender mounting screws to neg batt post and one from sender center tap to gauge. Just use some good wire you have and let it hang loose on the ground, or whatever, just to have a direct bypass of all existing wires. That's how you trouble shoot electrical/all problems. Isolate. Isolate, Isolate. This will tell you that you can eliminate wiring as the culprit and move to sender or gauge or gauge wiring as the problem.
