Questions about mounting and setup of my Prime 920

I’m new to the forum and have a Prime PM-920 that was given to me years ago. I’ve never mounted it anywhere, just have it on a portable wood stand and have a portable air tank set up for it with a large supply hose. I an now wanting to mount on the underside of my second floor deck roof. The roof has a 12/12 pitch with exposed cedar rafters. Any examples of mounting brackets out there for an application like this? Also, The peak of the roof where it will be mounted is approximately 16’ from where the tank will need to be located in the 2x12 floor joists. What size line and tank would be needed to get the full potential out of the Prime 920? Would a 1/2" line be enough over this distance?
