for #5, I think it goes to the heater but I was wondering how some of the 20b blocks have AN-fitting there instead of the hose fitting I have in the picture. Does it screw off? or do I need to cut it then tap it?

thanks much and happy holidays!

for the hose fitting going to the heater, how do some of you have AN-fitting instead of the hose fitting? do I need to cut it off then tap it? attached a pic of what i'm talking about.

i'll get to work in the meanwhile :)
