So I think I finally found the leak but I'm not quite sure. I put UV dye in with my last recharge and under examination with a blacklight, I found a seal that had traces of the dye around it. When I say around it, I mean just where the two (plastic?) parts meet. Not actually on the parts, but almost filling the crease of where the two parts meet. Now my question is, is this the culprit? Can a leak this small make my ref. pressure to be at 0. I've never dealt with this type of situation before and was wondering if this sounds about right. Thanks for your help boys!!
