This may be a silly question, but... I just got a kegging setup that included a single body dual gauge regulator. I also got a CO2 tank from CL with another similar regulator. I've read that the two can be connected to make a dual body for serving or force carbing at 2 pressures. Questions:
1) how on earth do I get the high pressure gauge off? I tried hand and wrench in both directions (assuming left and right handed thread). No dice. Also started trying to unscrew the small screws on the back of the gauge. This didn't seem right either.
2) do I need any other parts, nipple, etc to connect the two.
Tried searching and couldn't find this info
