I've been looking into DIY CO2
systems with the help of some people in this forum. I was referred to this article on a CO2
I did purchase "Fourmost Products" 3/32 Medium Bulkhead Fittings from Towerhobbies.com so I could drill a hole thru the cap of a 2-liter soda bottle and attach the tubing there. Now my question is, is that did I buy the right fittings? I can't really find 3/32 silicone tubing online. Or should I be looking for a different size of tubing? Should I have purchased the "large" bulkhead fittings? Any advice would be appreciated.
