I figured. Another odd question (I seem to be full of them!): Is there a pressure relief valve off of the air-assist solenoid? I ask because I picked up my Mini 24 yesterday and upon hooking up the air assist, it just blows and blows and blows, but not out of the air assist tube. I opened the back and it looks like there's supposed to be something there that is not. I have a call into support about the issue, but was wondering if you could offer any insight?
