Abstract
A fueling environment that 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 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 fuel dispensers detect leaks and provide alarms for the operator and help pinpoint leak detection that has occurred in the piping system proximate to a particular fuel dispenser or in between two consecutive fuel dispensers.

21. A method of detecting a leak in a fueling environment'"'"'s fueling distribution system with a fuel dispenser, said method comprising:
-
dispensing fuel throughout a fueling environment in an inner conduit of a double walled conduit;
capturing a leak from the inner conduit with an outer conduit of the double walled conduit;
returning fluid leaked into the outer conduit to an underground storage tank through a submersible turbine pump. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A fueling environment, comprising:
-
a fuel storage tank;
a submersible turbine pump associated with the fuel storage tank;
at least one fuel dispenser;
a double walled piping network fluidly coupling the fuel storage tank to the at least one fuel dispenser such that fuel is dispensed throughout the fueling environment in an inner conduit and leaks from the inner conduit are captured in an outer conduit and returned to the fuel storage tank through the submersible turbine pump. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
