The air rail comprises a housing defining an air passageway conduit therein. The conduit has a plurality of passageways therethrough with access to the passageways provided by a plurality of ports disposed in the housing, the main passageway being fed pressurized air from an air compressor discharge and discharging to the brake reservoir. A second passageway acts as a sensing and secondary air supply passageway, the outlet ports from this second passageway being engageable in a push to connect manner with air tubing leading to various air-using systems and devices, the outlets each being positioned as close as possible to the corresponding structure to which it is to be engaged. Further, the air rail may incorporate a fuel oil passageway therein, thereby providing for pre-warming of fuel for the engine.
