Before i ask, i have searched. Ive googled and ive searched some more. What in the fork is the fitting / thread pitch of the line / 90* fitting on the outlet side of the filter head? I’m installing a aux filter behind the stock filter, using the stocker as a pre-filter to the new 2mic. Filter. I just need to know what the damn thing is. Ive got new olives and i can get any crazy off the wall fitting i need from some friends at a fitting shop. This thing is just giving me the run around. SO if someone could tell me what i need to go from the outlet of the filter head and from the filter side of the IP supply line, in would really appreciate it. Happy Thanksgiving everyone!
