Fuel dispensing system with modular components

A fuel dispenser comprising:

• a fuel dispensing cabinet configured for dispensing fuel, and including a fuel dispensing hose,
• a fuel flow system in said cabinet and connected to a source of said fuel for controllably dispensing said fuel via said dispensing hose,
• a fuel flow control system further comprising:
• a computer display,
• a computer operatively coupled to said display,
• electrical pump control circuitry operatively coupled to said computer,
• a card reader operatively coupled to said computer,
• a receipt-producing device operatively coupled to said computer,
• power supply circuitry configured to provide power potentials to all components requiring said power potentials and,
• a module having one side configured for use by a customer, with said computer display, said card reader and said receipt-producing device being in usable relation with said one side, and said computer, said electrical pump control circuitry, said card reader, said receipt-producing device and said power supply circuitry mounted in said module,
• a recess in said fuel dispenser for slidably receiving said module,
• at least one first electrical connector mounted to a rear side of said module, said first electrical connector containing a plurality of first electrical terminals,
• at least one second electrical connector mounted in said recess in aligned relation with said first electrical connector, said second electrical connector containing a plurality of second electrical terminals configured for mating relation with said plurality of first electrical connectors,
• whereby said module is electrically coupled to said fuel flow system when installed in said recess.

A service station including a plurality of fuel dispensers each comprising:

• a fuel dispensing cabinet configured for dispensing fuel, and including a fuel dispensing hose,
• a fuel flow system in said cabinet and connected to a source of said fuel for controllably dispensing said fuel via said dispensing hose,
• a fuel flow control system further comprising:
• a computer display,
• a computer operatively coupled to said display,
• electrical pump control circuitry operatively coupled to said computer,
• power supply circuitry configured to provide power potentials to all components requiring said power potentials,
• said computer, said electrical pump control circuitry and said power supply circuitry mounted in stacked relation behind and to said display,
• a card reader operatively coupled to said computer,
• a receipt-producing device operatively coupled to said computer,
• a module having a front side configured as a front of said cabinet, with said computer display, said card reader and said receipt-producing device being in customer-usable relation with said front side, said module electrically coupled to said cabinet when inserted into place and electrically disconnected when removed,
• a non-volatile flash memory coupled to said computer, with configuration data for an associated said fuel dispenser and in said non-volatile flash memory available so that said configuration data may be removed from a defective said computer and re-installed into a replacement computer by disconnecting said flash memory from said defective computer and connecting said flash memory to said replacement computer.
