ABSTRACT:
A fuel system comprising a fuel tank having an opening. A cap is removably coupled to the fuel tank and operable for sealingly closing the opening to prevent ingress and egress of air through the opening. An overfill chamber is in communication with the fuel tank, and a hydrocarbon collection chamber is in communication with the overfill chamber. A valve is disposed between the hydrocarbon collection chamber and the overfill chamber. The valve includes a reference axis and is configured to permit fluid communication between the overfill chamber and the hydrocarbon collection chamber only when an angle between a vertical axis and the reference axis is less than about thirty-five degrees.
