It should be a simple matter to figure out where the ground fault is
and correct it at its source. It's either the connection between the
sender and the tank or between the tank and the body (or both.) Both
are easy to fix.
The only time I've seen a problem there was on a car where someone
had done repairs that required removing the gas tank. When they put
the tank back in, they didn't bother to reinstall the 4 clamps around
the edges. That made for some odd noises and an unsteady gauge, but
it only took 5 minutes to fix.
