Abstract
The invention concerns a float arm assembly for use in a vehicle fuel tank and a method of operating the float arm assembly to determine a level of fuel in the tank. First and second resistor cards are electrically connected in series and each includes a pivoting float arm with a float attached to an end. The first and second resistor cards, with separate floats allow the fuel level to be more accurately determined, especially in fuel tanks with complex contours and indentations in the tank wall that create dead bands in a single float type of arrangement.
