    It's most likely your gauge cluster, not the float. Does your gas gauge not work at all or does the needle itself move around?

    Welcome to the club Pacman. X2 on the guage being the culprit rather than the sending unit. The tank units very seldom give any trouble. I don't know of any easy fixes.
