ABSTRACT:
A method, fuel system, and a valve for facilitating the delivery of liquid fuel and fuel vapors from a fuel tank in fluid communication with a carburetor of an internal combustion engine. During operation of the internal combustion engine, the fuel tank is permitted to fluidically communicate the liquid fuel to the carburetor, and to vent the fuel vapors to one or more of a carbon canister, the atmosphere, and the carburetor. In contrast, when the internal combustion engine is not operating, the fuel tank is prevented from fluidically communicating the liquid fuel to the carburetor, and from venting the fuel vapors to one or more of the carbon canister, the atmosphere, and the carburetor, thereby preventing escape of evaporative emissions of the fuel from the fuel tank.
