Check the fuel tank to make sure it has a good ground. I chased this problem for a week before I found the fuel tank had a poor ground.

Running a wire from one of the mounting screws on the sender to a good ground on the body has fixed many a fuel gauges. Not the way the factory did it, but it works.
