A fluid leak detection system mounts to a hose line segment of the type comprising at least an inner carcass and an outer containment carcass separated from the inner carcass by a collection space. The system includes a housing defined by sidewalls externally mountable to the hose line segment and having an internal housing chamber in fluid communication with the collection space. A system sensor casing mounts through a sensor housing sidewall and a plurality of alternatively configured sensor units are provided, each interchangeably coupling with the sensor casing. The sensor units detect the presence of fluid within the sensor housing and communicate the fluid status of the chamber for remote evaluation.
