41 Claims

1. A system for monitoring and detecting leaks in at least one fuel-handling component in a service station environment, comprising: a fuel-handling component that carries fuel in a service station, wherein the fuel-handling component is surrounded by a fuel-handling component interstitial space having a first end and a second end, wherein the fuel-handling component interstitial space captures any leaks of fuel from the fuel-handling component; a vacuum-generating source fluidly coupled to the fuel-handling component interstitial space that generates a vacuum level in the fuel-handling component interstitial space starting at the first end and extending to the second end farther in distance away from the vacuum-generating source than the first end; and an end-of-line sensor coupled proximate the second end to sense if the vacuum level generated in the first end reaches the second end.
