Evaporative Check Valve: Description and Operation
Evaporative Emission Tube Shut Off Valve
PURPOSE
The Evaporative Emission (EVAP) tube shut off valve is located in-line between the evaporative emission valve and the EVAP canister, mounted
on the fuel tank by a bracket. It closes the flow path from the evaporative emission valve to the evaporative emissions canister during refueling to
prevent overfilling of the fuel tank.
NOTE: The evaporative emission tube shut off valve is serviced as an assembly with the evaporative emission valve.
