A mechanical fuel pump control system for controlling mechanical fuel pumps through a PC-based Point-of-Sales system utilizing a mechanical pump controller and a mechanical pump configurator is disclosed. The pump control system includes a pump control circuit board having a microprocessor with read-only-memory for storing operating code and a read-and-write-memory device for calculating and storing response data. The pump control system uses a configuration circuit board to condition output signals including preset limits, pump authorization signal and close valve signal, and to condition input signals including a pulse signal, a handle signal, and a motor return signal. A relay board controls the pumping process. The pump control system allows the POS application software to integrate pump control with other functions including register function, scanning, and inventory control in the POS computer. A feature of the present invention is that it allows the same POS system to control electronic and mechanical pumps through appropriate configurators.
