An apparatus for collecting liquid level data for any composition of fuel contained in a vehicle fuel tank and for transmitting this data via a multiplex bus to a central vehicle computer. A first capacitor stores a charge proportional to the level of a full fuel tank. A second capacitor stores a charge proportional to the instant level of the fuel in the tank. A micro-controller in communication with the first and second capacitors and with the multiplex bus for controlling the discharge of the capacitors, The micro-controller determines the absolute level of the fuel and transmits the data to the multiplex bus.
