1. A fuel theft detection system for detecting when fuel has been stolen from a vehicle'"'"'s fuel tank, the detection system comprising:

  • input means that is connectable to a vehicle'"'"'s fuel level sensor for providing an indication of the fuel level in the vehicle'"'"'s fuel tank;

    a controller connected to the input means;

    timing means for driving the controller to capture and record the fuel level at regular, pre determined intervals;

    storage means for storing the recorded data; and

    wherein the controller is arranged to calculate the average fuel level over a first period of time, and to then store the resulting average fuel level in the storage means for later analysis, so that any deviation in the fuel level in successive periods of time by more than a predetermined amount would suggest fuel theft, with the controller, after the fuel tank has been filled with fuel, also being arranged to determine the amount of fuel that has been dispensed into the fuel tank and to then enable a comparison to be made between the amount of fuel actually dispensed into the fuel tank and the amount of fuel alleged to have been dispensed into the fuel tank, with any discrepancy between these two values also suggesting fuel theft.
