So leak detector showed a slow leak right under the manometer but above the fill port. Called AOA to ask advice from one of the tech's named Shane, knew what the problem was and sent out parts which showed up Monday. Was going to work on it right away but something interesting happened while waiting for the parts. I changed the o-rings on my fill probe and then lubed my fill probe with silicone, filled the gun to 250bar (as recommended by Shane) now the gun leaks to 180-200bar area and stops there. I figured I would shoot it empty today and see how those new parts work (they are some type of adapter for the manometer, they look like o-rings with metal threading in the middle, I can post pictures if anyone is really interested). I just thought it was interesting that a bit of lube applied to the fill probe made a difference in how much pressure the gun would hold.
