A cover of a fuel supply module is adapted to disable a flow path through a designated port. An element is press-fit into the designated port to plug the designated port, and thermoplastic material is molded over an interface defined between the element and the designated port.

A primary metal terminal connects between a fuel pump and a drive circuit through a resin lid. A primary connecting point of the primary metal terminal connected to the drive circuit, is positioned around a drive control IC, and a primary exposed portion of the primary metal terminal, exposed to a receiving space of the resin lid is bent such that the primary exposed portion is resiliently deformable. A secondary metal terminal connects between an external circuit system and the drive circuit through the resin lid. A secondary connecting point of the secondary metal terminal connected to the drive circuit is positioned at a location that is further spaced from the drive control IC in comparison to the primary connecting point, and a secondary exposed portion of the secondary metal terminal exposed to the receiving space has a stiffness higher than a stiffness of the primary exposed portion.

A cooling system after engine shut-down includes a pump, a coolant duct for a coolant, and at least one component to be cooled. The coolant duct is associated with a fuel pump. A cylinder head for an internal combustion engine and a method for operating the cooling system after engine shut-down are provided.

A fluid transfer pump assembly that includes a motor enclosure assembly that forms a motor cavity sized to receive a motor. The motor enclosure includes a flame path that extends from an interior joint to an exterior joint. The interior joint faces the motor cavity and the exterior joint faces exterior of the motor enclosure assembly. A heat sink is located in the motor cavity of the motor enclosure assembly. A portion of the heat sink abuts the interior joint.

A marine propulsion system includes an internal combustion engine; a fuel reservoir; a pump that pumps fuel from the fuel reservoir to the internal combustion engine; and a fuel filter that filters the fuel. The fuel filter includes a canister and a fuel inlet that conveys the fuel adjacent to cylindrical sidewalls of the canister so that the fuel immediately spirally flows around and down the cylindrical sidewalls under centrifugal force and under force of gravity, and then is drawn radially inwardly through a filter element by the pump. A fuel outlet extends at least partially along a center axis of the canister and discharges the fuel from the canister. A drain is located at the bottom of the canister and configured to drain water that separates from the fuel as the fuel flows around and down the cylindrical sidewalls.

A fluid pumping device includes a barrel body and a piston mechanism. The barrel body has a cavity. The piston mechanism includes a piston member, a first annular plug, and a second annular plug. The piston member movably extends into the cavity. The piston member has two annular grooves where the first and the second annular plugs are disposed respectively. Each of the first the second annular plugs has an annular base section and an annular protrusion section. The annular protrusion section has a first outer annular abutting face. The annular base section has an outer annular base face. The first outer annular abutting face abuts against the inner wall of the cavity.
