GUAGE GOES TO EMPTY EVERY TIME TANK IS FILLED. MAY SHORTLY GO TO FULL OR STOP ANYWHERE IN BETWEEN. IS ACCURATE MOST OF TIME, BUT CAN FLOP AROUND UNDER ANY CIRCUMSTANCE.

    connector on fuel pump sending side,will eventually lead to fuel pump failure.GM is aware but does't care.New after market pump will have updated connector and works perfect.
