  • Patent number: 7555946
    Abstract: A sealed fuel level sensor for a fuel tank is provided. The sealed fuel level sensor includes a frame having a cavity therein. The sealed fuel level sensor further includes a variable resistor disposed in the cavity and operatively supported by the frame. The sealed fuel level sensor further includes a wiper disposed in the cavity for rotation relative to the variable resistor and for contacting the variable resistor. The sealed fuel level sensor further includes a cover connected to the frame to enclose the cavity. The cover includes an aperture extending therethrough. The sealed fuel level sensor further includes a bushing disposed within the aperture. The bushing having a body portion and a lip seal portion disposed on the body portion. The lip seal portion and the body portion having a bore therein. The sealed fuel level sensor further includes a float arm having an end extending through the aperture of the cover and the bore of the bushing and connected to the wiper.
    Type: Grant

The sealed fuel level sensor includes a cover connected to the frame to enclose the cavity and a float arm extending through the cover and connected to the wiper. The sealed fuel level sensor further includes a float connected to the float arm such that the float moves the float arm and the wiper relative to the variable resistor as a level of fuel increases and decreases in the fuel tank.
