Overfill Limiter (Two-way Valve) Operation
To test the two way valve for proper operation:
1.
Remove the 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.
