<p>A fueling environment that distributes fuel from a fuel supply (34) to fuel dispensers (32) in a daisy chain arrangement with a double walled piping system (50). 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 (64) 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 (32) or in between two consecutive fuel dispensers.</p> |
