i have a craftsman 33 gallon air compressor model number 919.167320 and it will not hold more than 30 psi. i just replaced the compression ring and a 2 o-rings on the rod/pump assembly. there are no leaks from anywhere on the tank. the air intake seems to stop sucking air once the tank hits around 25psi. is there a wrong way to put in the comp. ring? i unscrewed the torx bolt on top of the rod and placed the ring inbetween there and tightened the top down. im lost.....
