Abstract
A leak detection module (LDM) includes a housing that provides a cavity that is enclosed by a wall that has a hole. A valve is arranged within the housing and in fluid communication along a passage that extends between first and second ports on the LDM, the valve is movable between open and closed positions. A pump is arranged within the housing and in fluid communication with the passage. A fluid fitting extends through the hole and has a passageway that extends between first and second end portions. The passageway is in fluid communication with the pump, the fluid fitting provides one of the first and second ports. A fastener secures the fluid fitting to the wall.
