Fuel Tank Pressure Release Valve: Testing and Inspection
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 (located in-line, in the vapor line, next to the fuel pick-up on the left side of the
fuel tank).
3. Blow lightly into the inlet and the outlet. If air passes through after a slight resistance, then the valve is good.
