  • Patent number: 6505644
    Abstract: A dual barrel jet fuel pump assembly for a fuel tank in a vehicle includes a reservoir adapted to be disposed in a primary side of the fuel tank and having a top defining an overflow fuel level of the reservoir. The dual barrel jet fuel pump assembly also includes a first conduit conducting return fuel from an engine of the vehicle to the reservoir and a second conduit extending to an auxiliary side of the fuel tank. The dual barrel jet fuel pump assembly further includes a dual barrel jet pump disposed in the reservoir and having a first inlet operatively connected to the first conduit and a second inlet operatively connected to said second conduit to fill the reservoir with fuel from the primary side and auxiliary side of the fuel tank.

  • Patent number: 6230691
    Abstract: A secondary fuel pump assembly for a fuel tank in a vehicle includes a reservoir adapted to be disposed in the fuel tank having a top defining an overflow fuel level of the reservoir. The secondary fuel pump assembly also includes a conduit conducting return fuel from an engine of the vehicle to the reservoir and a jet pump having a discharge outlet in the reservoir and an inlet operatively connected to the conduit. The secondary fuel pump assembly includes an overflow fuel member defining a flow path for overflow of fuel in the reservoir and a guide member extending into the overflow fuel member and having at least one aperture extending therethough. The secondary fuel pump assembly further includes a guide disposed over the guide member and movable relative thereto to open and close the at least one aperture and a float connected to the guide to move the guide as a fuel level rises and falls in the reservoir.

  • Patent number: 6021668
    Abstract: This invention includes a combustion engine fuel level indication system operable at 10 mA or lower and without any contact resistance buildup. The present system utilizes a noble metal ink formulation for both contacts of resistive path and a conductive path. The resistive and conductive paths each having angled conductor lines which reduce the overall volume requirement for the noble metal ink composition used to make the paths. The invention also includes a wiper contact having spaced apart parallel tangs or fingers positioned so that a first finger engages a first conductor line along the conductive path and a second finger engages an adjacent conductor line along the conductive path to improve the make brake contact.
