In your first post you had a picture of your compressor and I believe the hose you where asking about is your air output from the compressor. It probably connects to an air dryer, maybe the vertical tank between the batteries. This dryer would then connect to the air storage tanks.
The compressor is water cooled but connected to the cooling system by 2 steel lines into the head of the compressor on the bellhousing side. I dont believe you should be getting any coolant in your air compressor output.
If you would like a manual there are at least a couple of military manuals that deal with the 903. You can find them on www.liberatedmanuals.com searching for TM-5-2815-24-34 (non turbo) and TM 9-2815-219-34 (VTA).
