ABSTRACT:
A gauge assembly includes an indicator for providing an indication of an amount of fluid in a tank and a stop-fill assembly for stopping the flow of fluid flowing into the tank once the fluid reaches a particular level. The gauge assembly has a shaft that rotates as the fluid level changes in the tank. The indicator translates the rotational position of the shaft into a fluid level. The stop-fill assembly moves from an open position, where fluid can flow into the tank, to a closed position, where fluid is prohibited from flowing into the tank, depending on the rotational position of the shaft.
