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 pump module.
The 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 may be serviced separately. If replacement is necessary, refer to Service and Repair.
