Fuel Check Valve: Description and Operation
Fuel Check Valve
PURPOSE
To keep liquid fuel from contaminating the Activated Carbon Canister.
OPERATION
Acting as a one-way valve, the Fuel Check Valve is designed to allow fuel vapors to enter the Activated Carbon Canister but block liquid fuel from
entering. A Rollover Valve is incorporated into the Fuel Check Valve. It insures that continuity of air passage does NOT exist when the rollover
valve is tilted more than 90°.
