Abstract
A fuel level sensor that includes a housing having a cavity formed therein, and a resistor element disposed within the cavity for creating a signal that may be utilized to indicate a liquid fuel level within a fuel tank. A float lever is associated with the housing adjacent a first end and adjacent a second end with a float is responsive to the level liquid fuel in the fuel tank. The float lever includes a first magnet that is disposed adjacent to the housing. A wiper and contact assembly is positioned generally adjacent to the resistor element to generate a signal that may be used to indicate a liquid fuel level. The wiper and contact assembly includes a second magnet that is magnetically coupled with the first magnet so that movement of the float lever is translated to movement of the wiper and contact assembly.
