Rollover Valve: Description and Operation
Fig. 1 Rollover Valve Location
The fuel tank is equipped with a rollover valve. The valve is located on the top of the fuel tank (Fig. 1).
The rollover valve will prevent fuel flow through the fuel tank vent (EVAP) hoses in the event of an accidental vehicle rollover. The EVAP canister
draws fuel vapors from the fuel tank through this valve.
The valve cannot be serviced separately. If replacement is necessary, the fuel tank must be replaced. Refer to Fuel Tank Removal/Installation.
