Apparatus for determining the fuel level in a fuel tank and for detecting the presence of water in the fuel tank. The fuel level in the tank is determined by detecting the change in capacitance between a pair of electrodes positioned with a generally vertical orientation so that as the fuel rises in the tank, an increasing area of the plates is adjacent to the fuel. Since the presence of water in fuel is very undesirable, the apparatus also includes means for detecting this water before it can effect engine performance and before it can effect the accuracy of the fuel level indicating circuitry.
