Sorry, friend, there isn't enough information here to make even a guess.

What kind and HP of air compressor?

What is the vessel you refer to, the tank?

Beside the vessel becoming hot, what are the problem(s) this is causing?

Please post a response as a comment here so I can follow the thread.

Thanks,

Bill
