Fuel gage troubleshooting

A couple of times in the past month fuel gage will go from reading correctly to needle going to 1/4 tank. It will stay like that for a few days then all of a sudden go to reading whats really in the tank. Sending unit was replaced with new AC part about 10 years ago. I'm thinking maybe sending unit going bad, gage itself, bad wire. Anything I might be overlooking. Thanks.

Re: Fuel gage troubleshooting

I havent had that problem yet. I did have no gauge for a year cause someone hooked the gauge directly to 12 volt on the fuse box insted of the gauge hook up on the box
