To reduce the amount of fuel vapor in a system by condensing fuel vapor in the system, in a fuel system.
A fuel system is provided with an oil feeding pipe 16, and the oil feeding pipe 16 has one end connected to an inlet of a fuel tank 12 and the other end having an inlet separated from the fuel tank 12. A vapor vent valve 41 for the fuel tank 12, and a vapor conduit 24 for communicating the vapor vent valve 41 with the inlet of the oil feeding pipe 16 are provided. When fuel is supplied to the tank 12 through the oil feeding pipe 16, vapor in the fuel tank 12 is drawn into the oil feeding pipe 16 through the vapor conduit 24, and at least a part of fuel vapor is condensed. A diaphragm driving valve may be used as the vapor vent valve 41. Moreover, a liquid/vapor separator may be provided, and fuel vapor can be drawn into the oil feeding pipe 16 through the vapor conduit 24 through the liquid/vapor separator.
