Yes, 3/8" male threaded fittings one each end. It is a line that goes from the engine mounted compressor to the line running down the frame. The piece I need is the rubber hose that connects the two hard lines. The hard lines have a compression bead and female fitting. Local parts house tell me they don't do air lines.
I haven't traced it out but I belive it goes to the rear.
The hose has been rubbing on the frame and developed a leak.
I've been searching on line for a service manual for this series truck. No luck so far.
