Fill limit vent valve (FLVV), Emissions control

Eaton’s Fill Limit Vent Valves (FLVV) prevents overfilling of the tank during a refueling event. Once the fuel tank has reached its maximum fill level the FLVV will close. Throughout the refueling event fuel vapor can escape through the FLVV to the canister.
