Thanks for the help (marker needs pre-2k pumpkit)! I was cleaning the marker today and when I removed the ans genx regulator parts of an old o-ring fell out of the vert asa. The o-ring on the ans reg is still intact; is this something i should be worried about? I think the previous owner may just have put an extra o-ring in the asa to accommodate his weird setup (ans reg wasn't screwed in all the way so that a way too small steel braided hose could fit the dropforward).
My Markers: ANS Gen X Autococker, ICD Alley cat, Dark Angel LCD, SL 68 II.
