ABSTRACT:
A fuel tank to be mounted on a vehicle and a canister are connected together via a two-way valve and a solenoid valve. Both valves are disposed within a valve casing which has a pair of connecting ports for connection to the fuel tank and to the canister, respectively. A bypass passage, which bypasses the two-way valve, to bring the two connecting ports into fluid communication with each other is provided inside the valve casing, and a solenoid valve is interposed in the bypass passage.
