    Abstract: The present invention involves a gear assembly of a fuel pump for improved supply of fuel to an automotive engine from a fuel tank. The assembly includes an inner gear and an outer gear matingly cooperating with the inner gear for rotation about an axis. The assembly further includes a pump cover including a cover surface adjacent the inner and outer gears and a pump body including a body surface adjacent the inner and outer gears opposite the pump cover. The cover surface has a primary inlet porting and a secondary outlet porting formed thereon and separated between seal areas. The body surface of the pump body includes a primary outlet porting and a secondary inlet porting separated between seal areas. In use, the inlet portings and the outlet portings of the pump body and the pump cover cooperate together, respectively, such that fuel entering through the inlet portings pass therethrough at a rate at which the gear assembly moves. Also, the outlet portings of the pump body and the pump cover cooperate together to allow fuel to pass therethrough at the rate at which the gear assembly moves.

    Abstract: A check valve assembly is disclosed for use in a returnless automotive fuel delivery system. The fuel delivery system includes a fuel tank having a fuel pump and a sender flange that provides access into the fuel tank. The check valve assembly includes an upper housing that is integral with an interior wall of the sender flange, a lower housing connected to the upper housing and a check valve body positioned between the upper housing and the lower housing. The assembly may also include a pressure relief valve positioned between the upper and lower housings and arranged parallel to the check valve body.
