Abstract
An in-dispenser leak pan provided inside the housing of a fuel dispenser. The leak collection chamber collects any fuel that leaks from fuel-handling components located inside the fuel dispenser above the pan. The pan is secondarily contained by an outer pan or container such that an interstitial space is formed therebetween. If a breach exists in the top part of the pan, the captured leaked fuel will be contained in by the outer pan in the interstitial space. The interstitial space of the pan is drawn under a vacuum level using a vacuum-generating source to monitor for leaks. If a leak is detected, a control system may generate an alarm and/or cause the submersible turbine pump to stop supplying fuel, or cause the dispenser product line shear valves to close, thereby only stopping fuel flow to the individual fuel dispenser containing the leak.
