Abstract: PURPOSE: When a fuel pump does not operate by a disorder of a motor or a pump, it is notified to a driver, and the fuel is supplied to an engine by a negative pressure of a fuel tank. CONSTITUTION: A fuel supplying device comprises a fuel tank, and an injector(53) injects fuel from the fuel tank. A pressure regulator(55) is installed between a return port(54) of the injector and the fuel tank to open when the fuel pressure is over a certain limit to maintain a certain value. A pressure sensor(56,57) detects pressure of the fuel supplied to the fuel tank and the injector. An electronic control unit(59) compares the pressure difference between the fuel tank and the injector, and notifies to the driver when the difference is less than a predetermined value, and decides fuel injection amount supplied to the injector by a negative pressure of the fuel tank.
