ABSTRACT:
A fuel tank comprising a fuel inlet pipe and a cap detachably attached to the fuel inlet of the fuel inlet pipe. A valve port interconnecting the interior of the fuel tank to a canister is formed in the fuel inlet pipe. A control valve controlling the opening operation of the valve port is arranged in the fuel inlet pipe. The control valve is normally closed. When a fuel pump nozzle is inserted into the fuel inlet, the control valve automatically opens, and the fuel vapor in the fuel tank is fed into the canister via the valve port.
