Liquid Vapor Separator: Testing and Inspection
The FVV valve assembly is grommet mounted to the top of the
fuel tank. It is used to vent vapors from the fuel tank to the EVAP system. The head portion of the assembly prevents the fuel tank from overfilling during refueling. The assembly also has a spring float, which prevents liquid fuel from entering the vapor delivery system under severe handling or vehicle rollover conditions. In the upright position the open bottom of the float will lift and shut off the orifice. Under severe handling conditions, the spring will push the float closed when angles allow liquid fuel to reach the orifice. In a rollover condition the weight of the open bottom float and spring pressure will close the orifice.
