Patent ID: 7555946

Claim:
A sealed fuel level sensor for a fuel tank, comprising: a frame having a cavity therein; a variable resistor disposed in the cavity and operatively supported by the frame; a wiper disposed in the cavity for rotation relative to the variable resistor and for contacting the variable resistor; a cover connected to the frame to enclose the cavity, the cover including an aperture extending therethrough; a bushing disposed within the aperture, the bushing having an annular body portion disposed about an axis and a coaxial annular lip seal portion affixed to the body portion wherein the lip seal portion covers an axial end surface of the body portion and peripherally encircles a portion of the outer peripheral surface of the body portion, the lip seal portion and the body portion having an axial bore therethrough; a float arm having an end extending through the aperture of the cover and the bore of the bushing and connected to the wiper, the lip seal portion engaging the float arm to form a seal; and 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.
