Abstract
A vent apparatus is adapted for use with a fuel tank to control venting of fuel vapor from the fuel tank. The vent apparatus comprises a fuel vapor vent outlet to discharge fuel vapor from the fuel tank. The vent apparatus comprises a normally open first valve module to serve as a fuel fill limit valve and close when the liquid level in the tank reaches a predetermined fill limit and a normally open second valve module to serve as a fuel fill limit valve and close when the liquid level in the tank reaches the predetermined fill limit. The first valve module and the second valve module cooperate to block communication between the fuel tank and the fuel vapor vent outlet when the vent apparatus is positioned in a non-tilted orientation relative to a horizontal and the level of liquid fuel in the fuel tank reaches the predetermined fill limit to close both valve modules.
