ABSTRACT:
An in-tank fuel level sender (26) for signaling the level of liquid fuel in a motor vehicle fuel tank (22). An enclosure (31) forming a hub of the sender provides an interior that is sealed against intrusion of fuel. An actuator (110, 122) is positionable on an exterior of the enclosure in correlation with liquid fuel level. A movement (52) within the interior of the enclosure follows the positioning of the actuator. An electric circuit element (62; 86) within the interior of the enclosure is operated by the movement to provide an electric characteristic for transmission through the enclosure to signal the liquid fuel level.
