Rollover Valve: Testing and Inspection

Overfill Limiter (Two-way Valve) Operation:

To test the two way valve for proper operation:

1. Disconnect the vapor hoses, and then remove the over fill limiter.
2. Connect a clean rubber hose to the inlet side of the valve.
3. Blow lightly into the inlet. If air passes through after a slight resistance, proceed to step 4.
4. Connect the clean rubber hose to the outlet side of the valve.
3. Blow lightly into the outlet. If air passes through without resistance, then the valve is good.
