るようにしたことを特徴とする燃料ポンプ。 Built into the fuel tank, the fuel in the fuel tank is sucked through the suction hole by a pump impeller, pressurized in the fuel passage along the pump impeller, and the air bubbles in the fuel sucked into the fuel passage are turned into bubbles. In the fuel pump configured to discharge the fuel from the discharge hole to the fuel tank side and then to the engine, a valve that operates by sensing the temperature of the fuel in the fuel tank is provided on the fuel tank side of the bubble discharge hole. A fuel pump characterized in that the opening area of the bubble discharge hole is changed by the operation of the valve.
