PURPOSE:To promote the starting and the driving efficiency in a machine with a fuel injection device by providing a fuel pipe with a gas discharge port to discharge gas contained in fuel. CONSTITUTION:A separator 6 is provided in a fuel-supply system between a fuel tank 2 and a fuel injection device 4. The separator 6A is constructed of a tank 20, a float 22, a needle 24, and others. When vapor is contained in fuel, the level of the fuel is dropped by the pressure of the vapor. Meanwhile, since the float 22 is brought down, a gas discharge port 28 to a canister 12 is opened, and the vapor is discharged to the canister 12 from the gas discharge port 28. This construction permits to supply only fuel to a fuel injection valve, and improve the starting and the driving efficiency. |
