25-30 psi is about right. It takes a while to fully carb.
To serve it, it needs about 25-30' of 3/16" line. I found some semi-rigid line years ago at McMaster-Carr, and it worked great because it was easy to curl up ontop of the keg.
Is 3/16" not the standard size tube? I was unaware I will need a bigger tube! I just want a Moscow nuke! Haha. Why do I need 25-30' of line when I have a 2 keg keezer.
