Abstract: PURPOSE: A gas fuel vehicle is provided to prevent leak of fuel from an injector by supplying residual fuel to an oil tank directly in stopping an engine, to improve start ability of the engine, and to reduce exhaust gas. CONSTITUTION: A gas fuel vehicle has a fuel supply line in which liquid gas fuel stored in a fuel tank(30) is pressurized by a fuel pump(32) and a regulator unit(20), supplied to an injector(11) of an engine(10) through a supply pipe(40), and burned. Non-burnt fuel re-flows in the fuel tank through a return pipe(50), passing through a pressure regulator(22) of the regulator unit and a return valve(51). The gas fuel vehicle includes a bypass pipe(100) communicated with the return pipe, bypassing the pressure regulator; a bypass valve(200) disposed on a side of the outer peripheral surface of the bypass pipe and controlled by an ECU(Electronic Control Unit,70); and a check valve(300) disposed on the bypass pipe to be separated from the bypass valve. The bypass valve opens a passage of the bypass pipe just when the engine stops. The check valve prevents countercurrent of fuel coming in the fuel tank.
