A fueling environment distributes fuel from a fuel supply to fuel dispensers in a daisy chain arrangement with a double-walled piping system. Fuel leaks that occur within the double-walled piping system are returned to the underground storage tank or a sump proximate the submersible turbine pump by the outer wall of the double-walled piping. This preserves the fuel for later use and helps reduce the risk of environmental contamination. Leak detectors may also be positioned in to fuel dispensers detect leaks and provide alarms for the operator, and help p...
1. A method of detecting a leak in a fueling distribution system in a retail fuel dispensing environment with a fuel dispenser, said method comprising:dispensing fuel throughout the retail fuel dispensing environment in an inner conduit of a double-walled conduit; capturing time leak from said inner conduit with an outer conduit of said double-walled conduit; returning fuel leaked into said outer conduit to a sump positioned proximate a submersible turbine pump in the retail fuel dispensing environment; detecting the leak at said sump; and routing leaked...
