Looking to build a fridge conversion kit, I can build one cheaper rather than buy a kit at this point. I had a 20lb co2 tank and reg given to me along with a sankey coupler and sankey kegs. Being that I'm brewing in keggles and fermenting in another keg(untouched). I'm going to build a sankey kegerator. My question is what diameter line and tail peices am I going to need along with wing nuts or regular nuts? Iv got really lucky we have a bev dispensing sales house here and its way cheaper than other shops.
