    摘要: A fuel-feeding system may preferably include a fuel tank containing liquid fuel; a fuel pump capable of pumping the liquid fuel contained in the fuel tank; a fuel injection valve capable of injecting the liquid fuel pumped by the fuel pump; and a three-way valve having a first port, a second port and a third port. The three-way valve is constructed so as to be switched between a first condition in which the first, second and third ports communicate with each other and a second condition in which only the first and third ports communicate with each other. The fuel injection valve is connected to the third external conduit at a position between the third port and the second relief valve, so that a pressure of the liquid fuel fed to the fuel injection valve can be switched between the first setting pressure and the second setting pressure when the three-way valve is switched between the first condition and the second condition.
