Tuning Cricket 2 Tactical - Dissasemble air tube and reg adjust help

Hey all - I'm looking to bump the reg up in my C2T 45 a touch. Removing the air cylinder has become a harder challenge with the bottle in front.

I'm familiar with removing the air cylinder and adjusting reg on the older Crickets, but the new bottle setup has me confused. 

I've removed the air, unscrewed the front bottle, loosened the screw holding the air cylinder and it freely rotates. There is a pin from the trigger guard into the air fill/gauge area so that you cannot unscrew that. I've tried removing screws 34 and 134 from the diagram:



So at this point I cannot unscrew the air tube and I am not able to tap it out forward easily. I do not want to force anything, so if anyone has done this please let me know what I am missing here.

Thanks.
