				So I borrowed a co-workers blasting machine to clean my new base intake with.  It had never been assembled or used.  So I assembled it (:sigh:) and I noticed a pressure valve at 130psi.  I figured since we normally leave the compressor at 100psi, I'm good.
 
 
Hook the air up, hit the ball valve, see it at 50 and rising, I walk off and here a loud bang then hissing.  I notice it blew the mostiure collector.  Just great!!
 
 
Since we already have one on our line, I remove it and lower my psi to 70'ish.  Seems to clog up alot??  Maybe I do need more pressure??  Raise to 85 and it blew the nozzle off the line.  I am now watching the hose in the driveway dance like a snake, while a dust cloud of walnut shells look like your following someone down a dusty 4x4 trail.
 
 
After getting stung by a flying object, run the mower outta gas, weedeater outta string, assembling this thing(PITA!), popping the moisture collector, and blowing the nozzle off the hose, I called it a night.
 
 
So... what psi should I be using?  30-40? or 100??  Any advice on trying to get this thing to work? _________________ 2008 GMC Z71

				| Clogging alot probably means you're still getting some moisture in the air. It's pretty hard to remove it all unless you have a killer $$ trap setup. |

				So try it at a lower psi tonight?
 
 
Yea, hard to capture all the mostiure, esp here in arkansas this year where crap is rusting sitting in tool boxes that havent rusted in 10+ years. |
