I'm running my gauge on negative ground, and it works fine. So I don't think polarity is the issue.

I'd look at the fuel gauge troubleshooting chart. It goes through a few different scenarios. It the tank ground is missing it goes to hard empty I belive. But if it's shorted it goes to hard full.

Some problems can be between the gauge/sender/tank and some internal the gauge itself.

Also make sure the gauge itself is grounded to the dash. New paint makes a wondeful insulator.
