Abstract
A fuel level sender () for signaling liquid fuel level in a fuel tank (). An enclosure () forming a hub of the sender provides an interior that is hermetically sealed against intrusion of fuel vapor and liquid. An actuator () is positionable on the enclosure exterior in correlation with liquid fuel level. A movement () within the enclosure interior follows the positioning of the actuator. An electric circuit element () within the enclosure interior is operated by the movement to provide an electric characteristic for transmission through the enclosure to signal liquid fuel level. A bottom reference rod () and stop () position the enclosure circumferentially within its mounting in a fuel pump module to cause the circuit element to signal zero fuel level when the stop is on the tank bottom wall and the actuator is in position corresponding to zero fuel level in the tank.
