  • Publication number: 20130341878
    Abstract: An instant work station, a hand truck frame combined with an extendable table designed and configured to receive a number of accessories. The table lip is integrally formed to create a unitary, one-piece structure that also serves as a frame to add strength to the table. Numerous pre-existing pin holes and locking mechanism in the table frame and hand truck frame allow the user to select a wide number of accessories for the invention. This permits the user to adapt the invention to fit specialized needs. The invention also includes locking mechanism for the user to secure a tool box or utility box for storing and securing tools. Securing the accessories on the invention will increase efficiency and ease of transportation.

  • Patent number: 6623237
    Abstract: A wear resistant fuel pump for a vehicle includes a pump section having a rotatable impeller and a plurality of plates disposed axially adjacent to and cooperating with the impeller to pump fuel therethrough. The wear resistant fuel pump also includes a motor section disposed adjacent the pump section and having a motor to rotate the impeller. The wear resistant fuel pump further includes an outlet section disposed adjacent the motor section to allow pumped fuel to exit therethrough. The impeller is made of a first compound and the plates are made of a second compound having an abrasion wear resistance on a surface thereof that improves abrasion wear characteristics therebetween.

  • Patent number: 6454521
    Abstract: A wear resistant fuel pump for a vehicle includes a pump section having a flow channel and a rotatable impeller cooperating with said flow channel to pump fuel therethrough. The fuel pump also includes a motor section disposed adjacent the pump section and having a motor to rotate the impeller. The fuel pump further includes an outlet section disposed adjacent the motor section to allow pumped fuel to exit the fuel pump. The pump section includes a plurality of plates disposed axially adjacent to and cooperating with the impeller. At least one of the plates includes a wear insert that improves abrasion wear characteristics therebetween.

  • Patent number: 6361691
    Abstract: A floated fuel strainer assembly for a fuel tank in a vehicle includes a strainer adapted to be connected to an inlet of either one of a fuel pump and fuel reservoir disposed in the fuel tank. The floated fuel strainer assembly also includes a float connected to the strainer to elevate the strainer off a bottom of the fuel tank as a fuel level rises in the fuel tank.

  • Patent number: 5787865
    Abstract: A passively filled reservoir in a motor vehicle fuel tank. The fuel tank has an electric fuel pump suspended therein and a tubular conduit through which surplus fuel is returned to the fuel tank. The passively filled reservoir includes a fuel containment vessel below the fuel pump, a passive fill port in the containment vessel juxtaposed a bottom panel of the fuel tank, a one-way valve in the passive fill port, a primary strainer around the containment vessel, and a secondary strainer inside of the containment vessel. The tubular conduit and a vapor discharge port of the electric fuel pump discharge into the containment vessel outside of the secondary strainer for recirculation to the fuel pump of surplus fuel and liquid fuel expelled from the fuel pump through the vapor discharge port. The primary strainer strains liquid fuel flowing through the passive fill port into the containment vessel.
