Abstract:
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.
