たことを特徴とする燃料噴射装置。 A fuel pump is equipped with a check valve that discharges fuel as the motor rotates and maintains a predetermined residual pressure even when the motor stops rotating, and the fuel pump discharges fuel according to the air suction pressure by the intake manifold. In the fuel injection device, the fuel injection device comprises a pressure regulator that regulates the pressure by the pressure regulator and maintains a predetermined residual pressure when the engine is stopped, and an injector that injects the fuel pressure-regulated by the pressure regulator into the engine. A fuel filter with an accumulator is installed in the flow path between the two, which integrates a filter section that removes dust from the fuel and an accumulator section that uses the residual pressure after the engine has stopped to ensure fuel pressure when starting the engine. A fuel injection device characterized by:
