Gas gauge woes..

You can also clean the clips on that factory jumper, and the areas on the sender and metal fuel line with sandpaper or steel wool. Check that the clips are snug and if not squeeze them in a little. Use fingers, not vise grips. Is the wire in the factory jumper broken?? Small hose clamps and copper wire to replace the factory jumper also work. spread a little grease where the jumper (factory or homemade) attach to the sender and fuel line.
