Compressor 921153101 will not go over 40 lbs pressure. 921153101 Craftsman Air compressor
I have the same problem as posted on 10/18/12 I checked the intake as suggested and found warm air pulsing. That suggests the piston rings are bad.
Are the rings available or do I have to buy the whole piston assembly?

Replacing piston rings on an air compressor could be a challenge without the instructions. I did some research on your question & added the links below. Hope this helps!
