Fuel Overflow Prevention System

The Attwood Fuel Overflow Prevention System is designed to prevent spills during refueling by utilizing a surge-free line that automatically shuts off fuel nozzles as the tank reaches capacity. For non-automatic nozzles, the system emits a gurgling sound to signal a full tank.

This innovative device features a ball-style check valve with internal baffling for optimal performance.
