Abstract: A multiple stage fuel strainer assembly for a fuel tank in a vehicle includes a strainer adapted to be connected to an inlet of a fuel pump disposed in the fuel tank. The multiple stage fuel strainer assembly also includes a valve connected to the strainer to allow fuel to flow through the strainer to the inlet when an external surface of the strainer is restricted with contaminants in the fuel.

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.

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.

Abstract: A fuel sender including a container in a fuel tank of a motor vehicle and, in the container, a filter, a fuel pump, a jet pump, and a pressure regulator. An upstream side of the filter and the fuel pump are connected through a first passage in a first end wall of the container. A downstream side of the filter is connected to an interior volume of the container through a convoluted second passage on a second end wall of the container. A pressure regulator on the second end wall of the container maintains fuel pressure at a substantially constant magnitude by variably restricting flow through the second passage. A venturi throat in the second passage aspirates fuel from the fuel tank into the container. The efficiency of the jet pump is maximized by minimizing the length of the convoluted second passage. Vibration isolating seals minimize the transfer of vibrations and pressure pulsations to the container.
