A fraud detection system within a fuel dispenser includes the ability to measure the amount of fuel dispensed through the fuel dispenser. The measurement is compared to a value independently created representing what the amount of fuel dispensed should approximate. If the values are not comparable, an alarm may be generated to indicate that the fuel dispenser has been modified to perpetrate fraud upon the customers. In particular, a reference used in the comparison is created using on an output from a storage tank sensor. The storage tank sensor, during the dispensing of fuel provides an independent number related to the amount of fuel actually dispensed that can be compared to the reported amount of fuel dispensed.
