Abstract: A fuel supply assembly includes a reservoir, primary and secondary fuel pumps and a pressure regulator. The secondary fuel pump has first and second inlets, and an outlet. The first inlet receives at least some fuel discharged from a pressure regulator outlet, a nozzle communicated with the first inlet so that a flow of fuel through the nozzle creates a drop in pressure in the area of the second fuel inlet to draw fuel from the supply of fuel through the second inlet and the fuel drawn in through the second fuel inlet is combined with the flow of fuel from the nozzle and the combined fuel flows are discharged from the secondary fuel pump outlet and into the reservoir. The primary fuel pump may be located outside of an interior of the reservoir and the secondary fuel pump may be connected to the reservoir by rigid or flexible conduits.

Abstract: In at least some implementations, a jet pump includes a main body having a first inlet, an inlet passage communicated with the inlet, a second inlet, an intake passage communicated with the second inlet, an outlet, and an outlet passage communicated with the outlet and with the intake passage, a jet carried by the main body and having a jet inlet communicated with the inlet passage so that fluid flowing in the inlet passage flows through the jet inlet, and a jet outlet having a flow area less than the jet inlet and less than the inlet passage. The main body is formed in one piece and the jet is a separate piece of material that is inserted into the inlet passage after the main body has been formed.
