Abstract:
A returnless fuel delivery module for supplying fuel to an engine from a fuel tank, the fuel delivery module comprising:a fuel reservoir;a sealed filter housing defining a main fuel filter chamber, the main fuel filter chamber containing a main fuel filter, the filter housing being mounted to the fuel reservoir;a fuel pump located within the fuel reservoir for pumping fuel from the fuel reservoir;a fuel pump outlet conduit in fluid communication with an outlet of the fuel pump and the main fuel filter chamber for routing fuel from the fuel pump to the main fuel filter chamber;a filter housing outlet conduit in fluid communication with the main fuel filter chamber and a fuel line for routing fuel from the main fuel filter chamber to the engine;a pressure regulator in fluid communication with the main fuel filter chamber and a jet pump fuel inlet conduit, the pressure regulator suitable for routing a portion of fuel from the main fuel filter chamber and to the jet pump fuel inlet conduit when a threshold pressure is reached in the main fuel filter chamber; anda jet pump located within the fuel reservoir, the jet pump having a fuel intake chamber in fluid communication with the jet pump fuel inlet conduit for receiving the portion of fuel from the main fuel filter chamber and routing the portion of fuel past a venturi opening to draw fuel from the fuel tank through an inlet orifice in a wall of the fuel reservoir into a jet pump fuel outlet chamber and through a jet pump outlet conduit into the fuel reservoir, the jet pump outlet conduit including a one-way valve which allows fuel flow from the jet pump outlet conduit into the fuel reservoir while preventing fuel flow from the fuel reservoir into the jet pump outlet conduit.
