*EDITED* I had a brain-fart and screwed up the suggestion. I fixed it now.

Do this first, take the lead from the sender (at the tank end) and ground it out with a jumper to something solid on the truck. The guage should then go to "empty". If it does, the problem is at the sender and not the resistor. Double-check the ground for the sender too, jumper from the sender ground tab to the same solid grounding point on the truck.

Man I hate it for you. I had a myriad of electrical issues, and spent about 2 months tracking most of them down at the end of last year. After unplugging and plugging every harness, plug, etc, using silicone dielectric grease on every connection, replacing numerous fuses and bulbs, a switch here and there, I finally have a solid electrical system. The tank sender issue was the last one I tackled, and I only did that last weekend.
