Abstract
A fuel sender assembly using a wiper contact to generate a resistance proportional to fuel level in a fuel tank has a bent float rod engaged by a fork and a bore of a carrier element which rigidly carries a spring contact. The spring contact slidably engages a resistor on a resistor card within a housing. The carrier element extends through a slot in the housing such that it abuts the ends of the slot to provide rotational limits for the float rod. The resulting fuel sender assembly can be installed in a fuel tank with no electrical calibration being needed.
