A fuel dispensing system is disclosed that includes an above-ground interface and a below-ground dispenser. The interface may provide for selecting fuel types and grades and performing conventional fuel purchase transactions. The below-ground dispenser includes control circuitry, one or more pumps and metering components that supply fuel as desired to the above-ground interface. The above-ground equipment is coupled to the below-ground equipment via one or more break-away assemblies. In the event the above-ground equipment is impacted or torn from the base, the break-away assemblies interrupt the flow of fuel and power. The installation may be serviced by repair and/or replacement of the above-ground interface without adversely affecting the underground dispenser system. |
