Fuel Tank Pressure (Two-Way) Control Valve

Overfill Limiter (Two-way Valve) Operation:

To test the two way valve for proper operation:

1. Remove the [1][2]overfill limiter mounting bolt.
2. Disconnect the vapor hoses, and then remove the over fill limiter.
3. Blow lightly into the inlet and the outlet. If air passes through after a slight resistance, then the valve is good.
