Abstract: A fluid pump includes a motor, an inner gear rotor and an outer gear rotor. The inner gear rotor is driven for rotation about an axis by the motor and has a plurality of outwardly extending teeth. The outer gear rotor has a plurality of inwardly extending teeth that are engaged by the teeth of the inner gear rotor so that the outer gear rotor is driven for rotation about a second axis when the inner gear rotor rotates. At least one of the inner gear rotor and the outer gear rotor is formed from a plastic material.

Abstract: An in-tank fuel pump and reservoir canister module having a fuel filter mounted in the module base adjacent the bottom of the tank and defining a filter chamber having an outlet connected to the inlet of an electric fuel pump received directly in the tank exteriorly alongside of an upright overflow-type reserve fuel canister. A canister bottom outlet is closed by a flow controlling valve and/or by an always-open restricted orifice communicating with the filter chamber for returning engine bypassed reserve fuel from the canister reservoir to the pump inlet, either continuously and/or only when a low level supply of fuel in the tank to the filter is interrupted.

Abstract: An engine fuel delivery system and method, and for use therein, an in-tank fuel pump and reservoir canister module assembly having a primary fuel filter mounted in a base subassembly adjacent the bottom of the tank and defining a filter chamber in the base having an outlet connected to the inlet of an electric fuel pump received directly in the tank exteriorly alongside of an upright open top reserve fuel canister. The pump outlet is connected to a bypass pressure regulator which discharges fuel in excess of engine demand into the canister. The canister has a bottom outlet mounted on the base subassembly and closed by a flow controlling valve and/or by a restricted orifice communicating the canister outlet with the filter chamber for returning bypassed reserve fuel from the canister reservoir to the pump inlet, either continuously and/or when a low level supply of fuel in the tank to the primary filter is interrupted, such as during cornering or going up or down a steep hill or incline.
