  • Patent number: 7387111
    Abstract: An in-tank fuel supply unit is provided for supplying fuel from a fuel tank to an engine. The fuel supply unit generally comprises a fuel delivery module and a jet pump assembly selectively attachable to the fuel delivery module. The fuel delivery module has a housing defining a reservoir and includes a fuel pump for pressurizing fuel in the reservoir. The jet pump assembly has a suction tube defining a suction chamber and a nozzle situated inside the suction chamber. The nozzle receives pressurized fuel from the fuel pump and sprays the fuel from a nozzle tip at high velocity to draw additional fuel into the suction chamber through an inlet formed in the suction tube.

  • Patent number: 7007678
    Abstract: A fuel supply system and fuel filter for a vehicle prevent bleed down of the fuel filter and minimizes the amount of any air or vapor delivered to the fuel supply line. The fuel filter includes a housing enclosing a filter media. The filter includes an inlet for receiving fuel from the fuel pump. The filter also includes first and second outlets. The first outlet supplies filtered fuel to the fuel supply line. The second outlet supplies filtered fuel to the jet pump. In this way, by providing a single outlet from the fuel pump to the fuel filter, and providing two outlets from the fuel filter which separately leads to the fuel supply line and the jet pump, bleed down is prevented and vapors within the fuel supply line are reduced.

  • Patent number: 6907899
    Abstract: The present invention provides a fuel delivery system for a saddle fuel tank wherein a fuel pump and a jet pump are positioned within an active side of the tank. The jet pump is directly driven by the fuel pump to draw the fuel from a passive side of the tank to the active side of the tank.

  • Patent number: 6675778
    Abstract: A fuel sender assembly comprises an electric fuel pump held in a mounting plate which is, in turn, mounted in a fuel tank, such as an automotive fuel tank. The mounting plate includes a chamber wall that defines a pump chamber having an inboard end and an outboard end. The electric fuel pump is received in the pump chamber such that an inlet end, which includes a fuel inlet, is disposed within the fuel tank adjacent the inboard end of the pump chamber. The outlet end of the fuel pump includes the electrical terminals and is disposed adjacent the outboard end of the pump chamber so that the electrical terminals are accessible outside the fuel pump for connection to an external power source. A hermetic seal is formed between the fuel pump and the chamber wall to prevent vapors from escaping through the pump chamber. The fuel sender assembly permits electrical connections to be made to the fuel pump without requiring wires within the fuel tank.
