Before you delve into the gas gauge, check the sender. Mine had pin holes under where the rod wrapped around the float. Drained it, soldered it and now it's fine. The gauge can be replaced, individually or all 4, but be careful if you remove and replace the individual gauge. If it moves a bit as you tighten it into the case it can short out and melt your wiring.... Yes, I've done it.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
