    The top photo is the condenser for the air conditioning and the other one looks like a quick release valve for the air brakes.

    It's the dryer or receiver. Needs to be changed every time the system is opened up.

    The first one is the “Dryer” for the air conditioning. The second one is the quick air release valve which is supposed to be mounted. Depending who does your level 1 inspection, but that’s a OOS until mounted.

    Condenser looks like a small radiator or cooler. It’s cools the Freon. Usually mounted somewhere in front of the radiator.

    Second one is pressure protection valve. It will not allow air out of tank until reaches you 60 or 70 PSI. Common Sealco P/N is 140270.

    Thank you all for the input. I identified the valve as part:
    070-KN31000

    Is it supposed to "leak" air because it has a small pinhole size opening that even the new part has as well.

    Thanks again

    That pinhole is probably there for a relief when the valve opens and closes.

    Pressure protection valve - used to isolate aux.air from brake air in case of emergency air loss. Is it in between the two air tanks? I can't see where it's going in the picture.
