A fuel system that provides fuel to an internal combustion engine includes a fuel tank and a fuel pump configured to receive fluid from the fuel tank and supply pressurized fluid to the engine via a fuel filter. The filter receives fuel from the pump and provides filtered fuel to the engine. The filter is disposed in a filter chamber of a filter housing. The filter housing includes a fuel inlet that directs fuel received from the fuel pump into the filter chamber, a fuel outlet that directs filtered fuel received from the fuel filter to the fuel supply line, and a bypass outlet that directs fuel not drawn into the fuel filter by the internal combustion engine to a fuel pressure regulator. The regulator receives the unfiltered fuel from the bypass outlet and returns the unfiltered fuel to the fuel tank.

A vehicle fuel tank assembly includes a fuel tank and an electrically conductive top plate that closes and seals a fuel-fill opening in the fuel tank. The top plate includes electrical dissipation structures and features that allow for electrical charge dissipation of the fuel tank to an external structure such as the vehicle chassis. The dissipation structures include an electrically insulative carrier that is partially embedded in the top plate using an overmolding process, and an electrical conductor that is supported by the carrier. The electrical conductor provides an electrical connection between the top plate and the chassis that is independent of the fuel tank and the fuel tank mounting structure.

Vehicle fuel tank assembly

A fuel tank assembly includes a fuel tank and a fuel pump module. The module supports a fuel pump that delivers fuel to an engine of a vehicle, and includes a module housing that provides a cavity that receives the fuel pump, a reservoir that is actively filled with excess fuel discharged from a fuel pressure regulator, and a fuel return passageway that directs excess fuel discharged from the pressure regulator to the reservoir. When the fuel tank assembly is inverted, as may occur when the vehicle is operating under certain dynamic conditions, the discharged fuel is retained within the reservoir, and is supplied to the fuel pump inlet via a wicking filter that extends between the reservoir and the fuel pump inlet. As a result, engine stall due to lack of fuel during certain dynamic conditions can be delayed or avoided.

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 vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes a jet pump choke that is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The jet pump choke includes include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.

A vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes, a first choke and a second choke. The first choke is disposed in the feed tube and provides filtering of the fluid and a reduction of pressure within the feed tube. The second choke is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The first and second chokes each include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.

A fuel supply system includes a fuel pump having an inlet configured to pick up fuel and an outlet configured to discharge fuel. A pressure vessel is in fluid communication with the outlet of the fuel pump such that fuel is directed from the fuel pump into the pressure vessel, the pressure vessel having an outlet port. A pressure regulation valve subassembly is detachably coupled with the outlet port via a male-female interface that positively locks against axial separation upon axial coupling in a first orientation and relative rotation of less than 360 degrees to a second orientation. A reservoir defines an internal space at least partially receiving the fuel pump, the pressure vessel, and the pressure regulation valve subassembly. The reservoir includes an interior wall that obstructs rotation of the pressure regulation valve subassembly from the second orientation to the first orientation.

An electrical connector for a modular electrical connection assembly for a fuel system includes a first leg portion and an adjacent second leg portion, each leg portion defining a cavity. The cavity of the first leg portion is configured to receive and maintain a first connector terminal and the cavity of the second leg portion is configured to receive and maintain a second connector terminal without the use of a seal fluidly separating the first connector terminal from the second connector terminal. The first connector terminal and the second connector terminal are concurrently operable with the fuel system.
