I'm going to check the wiring from the sending unit to the cluster and if all is good then I'm going to replace the sending unit with one from CSC like pcspecialist did and see if that fixes it. If it's not wiring then it has to be either a bad/flaky rheostat on the stock sending unit or faulty gauge cluster and I'm betting on the rheostat if the wiring is good. I'll try to remember to keep you posted on what fixes it.

Check to make sure your tank is not grounding out to the frame. I had the same issue and it turned out that from the factory they had installed the rubber isolator on top the tank instead of between the tank and frame. This is how it was installed from the factory. A quick way to test it is to just remove the bolt and lift the tank off the frame to see if it works again. That's how I figured it out that it had to do with the tank grounding out.
