A fuel delivery module with an integrated fuel filter is disclosed. The fuel delivery module can be mounted in a fuel tank for supplying fuel from the fuel tank to an engine. The fuel delivery module includes a fuel reservoir, a sealed main fuel filter housing, a fuel pump, a pressure regulator, and a jet pump. The main fuel filter housing is mounted to the fuel reservoir and defines a main fuel filter chamber that contains a main fuel filter. The fuel pump is located within the fuel reservoir for pumping fuel from the fuel reservoir through a fuel pump outlet conduit and into the main fuel filter chamber. A filter housing outlet conduit is provided for routing fuel from the main fuel filter chamber to the engine. The pressure regulator is in fluid communication with the main fuel filter chamber and a jet pump fuel inlet conduit 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. The jet pump has a fuel intake chamber in fluid communication with the jet pump fuel inlet conduit for receiving fuel from the main fuel filter chamber and for routing the 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 includes 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. The fuel delivery module maintains a minimum level of fuel in the fuel reservoir to provide a continuous source of fuel to the fuel pump when the fuel tank fuel level is low or when vehicle operations, such as cornering, braking, acceleration, or slope parking, would cause the fuel tank fuel level to fall below the inlet of the fuel pump.
