Claims (1)
燃料を吸込管を介して吸込みつつ、エンジン側に
向けて吐出させるポンプ本体と、該ポンプ本体の
吐出側に設けられ、該ポンプ本体から吐出される
燃料の脈動を抑えるべく、内部がダイヤフラムに
よつて燃料室と圧力室とに画成されたフユーエル
ダンパとからなる燃料ポンプにおいて、前記フユ
ーエルダンパの圧力室には導管の一端側を接続し
、該導管の他端側を車両の水浸入防止可能部位と
接続したことを特徴とする燃料ポンプ。 A pump body is located outside the fuel tank and sucks the fuel in the fuel tank through a suction pipe and discharges it toward the engine. In order to suppress the pulsation of the fuel, the fuel pump includes a fuel damper whose interior is defined by a diaphragm into a fuel chamber and a pressure chamber, and one end of a conduit is connected to the pressure chamber of the fuel damper. A fuel pump characterized in that the other end of the conduit is connected to a part of a vehicle that can prevent water intrusion.
