ABSTRACT:
An in-tank type electrically operated fuel pump assembly includes an electric motor which is controlled by a control circuit located externally of a pump housing and adjacent to a passage through which fuel is fed from the pump. A case in which the control circuit is enclosed is not subjected to a high pressure, assuring stable protection of the control circuit for a long period of time. Furthermore, the control circuit is effectively cooled by the flowing fuel.
