If your gas gauge is not working it could be only a few things. If you can take the single wire that is attached to the sending unit and touch it to ground with the key in the on position it should make the gauge needle swing to the other extreme. If it does not move at all then the sending unit is defective!
Rubber seal between tank and sender is ARA1502
Locking ring is ARA1501
