Abstract:
In at least some implementations, an assembly includes a reservoir, a primary fuel pump having an inlet in communication with the reservoir's internal volume, an outlet, a motor and a pumping element driven by the motor and a secondary fuel pump with a body having first and second inlets and an outlet. The first inlet receives fuel from the primary fuel pump and a nozzle is communicated with the first inlet and fuel flows out of the nozzle into the body via the first inlet. The second inlet is in communication with the reservoir inlet, and the outlet is in communication with the internal volume. The flow of fuel through the nozzle draws fuel from the fuel source through the second fuel inlet and that fuel is combined with the flow of fuel from the nozzle and discharged into the reservoir.
