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.

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.

In at least some implementations, a device includes a fuel system component having a body through which fuel flows, and a retention member body connected to the body of the fuel system component, the retention member body having one or more retainers that are flexible and resilient, and that extend outwardly from the retention member body and that are arranged to engaged spaced apart portions of an interior of a fuel tank to retain the position in the fuel tank of the fuel system component.

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.

A self-relieving choke valve system for a carburetor of a combustion engine automatically opens a choke valve after a successful engine start up and permits the choke valve to automatically close when the engine is shut down. The self-relieving choke valve system is preferably passive in nature and preferably self contained to the carburetor. It has a vacuum motor which preferably receives a vacuum signal from a vacuum source derived from the operating engine to open the choke valve. A lost motion linkage of the self-relieving choke valve system permits the choke valve to fluctuate between a closed position and a slightly open engine start up position without any intervention by the vacuum motor while the engine is being started.

A fuel removal system for a carburetor with a float bowl carried by a body having a channel extending from the float bowl to the exterior of the carburetor body. An outlet tube is positioned within the channel and is movable from a first position wherein liquid fuel can be removed from the fuel bowl to the exterior of the body, and a second position wherein the outlet tube does not communicate with the float bowl.
