Ok, here is the deal, the stock vacuum line comming out of the pumkin, should it leak air out when the compressor is on for the arb?

Are you talking about the diff vent tube? And when you say the ARB compressor running do you mean the locker in the ON possition also. If the Locker is in the off position with the compressor running and air is coming out of the VENT not the Vacuum line, then you have other issues. :flipoff2:

If air is coming out of the vent tube on the pumpkin you have blown the seals in the ARB and need to get it fixxed before you use it again. What air pressurea are you running it at?

I just had this issue. I could hear air leaking out the diff. breather vent tube. Turned out the fitting where the copper line goes into at the housing was leaking on the inside. Needed to replace the ferrule & tighten it up & all was good.
