I'm in the process of setting up a kegging system using 4 Corny kegs. I'd like to keep the kegs in an old fridge (standard GE 20.5 cu ft, two-door fridge/freezer circa 1993). To save space inside the fridge I'd like to run the C02 gas line into the fridge from the outside, preferably through the side of the fridge. I'm guessing that there is only insulation on the side of the fridge, but this is only a guess. Anybody done this and/or know anything about doing this? Cheers!
