I suspect what you actually have is a tank check valve that's leaking.

Dump all the air from the tank with the compressor off, remove, clean and / or replace the tank check valve, and that will most likely solve your problem.

See the pages on unloader valves and tank check valves on this site for a better understanding of how they work together.

central Pneumatic 94667 leaking below the black box/switch, won't shut off unless unplugged. Is there a way to replace this part since this model is discontinued?? Thanks :)

If I can find a source for you for that part, I will so advise.
