ABSTRACT:
A pressure reducing valve with a breathing hole is incorporated in a dome provided on the upper wall of a fuel tank and it is open to a vent pipe. A fuel cut valve with a leak hole is provided proximately to the pressure reducing valve. Opening-closing means are also provided on the port side of the fuel cut valve so as to actuate both the pressure reducing valve and the fuel cut valve. When an engine is running, the pressure of return fuel is applied to a float of the opening-closing means, whereby the pressure reducing valve is opened and the fuel cut valve is closed. When the engine is stationary, due to no pressure of return fuel, the float goes down to close the pressure reducing valve and open the fuel cut valve.
