Abstract
A pump housing contains a pump that draws fuel from an underground storage tank to deliver fuel to fuel dispensers in a service station environment. The pump is coupled to a double-walled riser pipe that carries the fuel from the underground storage tank to the pump. The double-walled fuel piping contains an inner space that carries the fuel and an outer annular space that captures any leaked fuel from the inner space. The outer annular space is coupled to a vacuum created by the pump to determine if a leak exists in the outer annular space. An alternate submersible turbine pump has a double-walled housing with a pressure sensor disposed in the interstitial space of the double-walled housing. A vacuum may be created therein to determine if leaks are present in the housing of the submersible turbine pump.
