Rollover Valve: Testing and Inspection

Overfill Limiter (Two-way Valve) Operation:

Procedure to test the Overfill Limiter (two-way valve) for proper operation:
1. Remove the [1][2]overfill limiter mounting bolt.
2. Disconnect the vapor hoses, and then remove the [1][2]overfill limiter.
3. Blow lightly into the inlet and the outlet. If air passes through after a slight resistance, then the valve is good.
