1. A fluid carrying conduit equipped for leak detection, which comprises a conduit surrounded around its circumference with a pliable fluid permeable conductive material, and which has a series of parallel insulated electrical conductors disposed generally longitudinally along the conduit and wrapped around the outside of said pliable conductive material, said insulated electrical conductors having bare conductor elements exposed at adjacent areas of insulated conductor material on the side of the insulated conductor material that is adjacent the pliable conductive material wherein the conductive material is adapted to be expanded by the pressure of leaking fluid and thereby contact the conductor elements at adjacent exposed areas.
