    • A fuel pump includes a case member defining a fuel passage and a discharge-side cover connected to the case member and defining an outlet port. A pump section has an inlet port and is connected to the case member. A motor section is housed in the case member for driving the pump section. A positive electrode terminal and a negative electrode terminal are supported by an insulative terminal support member fixed to the discharge-side cover. Base portions of the positive and negative electrode terminals are covered by insulative portions. The insulative portions are fitted in fitting holes of the discharge-side cover. The discharge-side cover has guide portions on its inner surface. The terminal support member has engagement projections on opposite side walls thereof. The engagement projections are guided by the guide portions to restrict the discharge-side cover from rotating with respect to the terminal support member.
    • 燃料泵包括限定燃料通道的壳体构件和连接到壳体构件并限定出口的排出侧罩。 泵部分具有入口并连接到壳体部件。 电动机部分容纳在用于驱动泵部的壳体部件中。 正极端子和负极端子由固定到排出侧盖的绝缘端子支撑构件支撑。 正极端子和负极端子的基部被绝缘部分覆盖。 绝缘部分安装在排放侧盖的装配孔中。 排出侧盖在其内表面上具有引导部分。 端子支撑构件在其相对侧壁上具有接合突起。 接合突起被引导部引导,以限制排出侧盖相对于端子支撑构件旋转。
