Rollover Valve: Description and Operation
Rollover Valve Location
The fuel tank is equipped with 2 rollover valves. The valves are located on the top of the fuel tank.
The rollover valves 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 these valves. The valves are not serviceable. If replacement is necessary, the fuel tank must be replaced.
