Hi Ric, I run three tanks of one tank of CO2. Radids Beer Equipment at www.4rapid1.com sells some equipment that works. Besides Tanks and regulators they sell CO2 hose at $35.00 per 100 foot. The size is 5/16. They also sell Modular CO2 distributors that can be hooker in series as many as needed. I then downsize the hose after the distributors to 3/16 size that is normal. Hope this helps Ray
