Abstract
A float operated fuel level sender for an automotive vehicle fuel tank includes a molded plastic case secured to a conductive plate. A potentiometer assembly (electrically connected to a fuel gauge) includes a resistor secured within the plastic case and a wiper element movable with the float arm along the length of the resistor. The wiper element is electrically and mechanically connected to the float arm which in turn is connected through a contact element to the conductive plate to provide an electrical ground return. The plastic case has an integral resilient finger formed therein which is biased against the end of the float arm to urge the contact member against the conductive plate thereby assuring a good ground connection.
