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.

Abstract: A fuel supply device includes a main body, fuel chamber, fuel supply pipe and a fuel valve. The main body has a main bore with an inlet for air and an outlet through which a fuel and air mixture flows. The fuel chamber retains a supply of fuel. The fuel supply pipe has a passage communicating with the main bore and through which fuel from the fuel chamber flows to the main bore. And the fuel valve has a valve seat, a valve element movable relative to the valve seat between an open position and a closed position, an inlet upstream of the valve seat and is in communication with the fuel chamber, and an outlet downstream of the valve seat. The outlet is coaxially aligned with the passage of the fuel supply pipe and the fuel valve is electrically operated to move the valve element.

Abstract: In at least some implementations, a charge forming device includes a main body, a throttle valve and an adjuster. The main body includes a main bore through which fluid flows for delivery to an engine. The throttle valve is carried by the main body and moveable relative to the main bore to control fluid flow through the main bore. And the adjuster is moveable relative to the throttle valve and engageable with the throttle valve to adjust the range of motion of the throttle valve. In at least some implementations, the adjuster limits the range of motion of the throttle valve when the adjuster is engaged with the throttle valve.

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.
