First off, why aren't 3 letter words searchable?
I am upgrading my kegerator to a two-tap version. When shopping for gas line, is there a standard tubing length? I know you have to calculate distance from keg to tap for beer line, but if I go 4' per line (conveniently, I happen to have 8' here already) am I OK? It's a standard half-fridge with the tower placed on the bar.
