I have a Sanyo 4912 fridge that I've converted to a kegerator, and for the sake of flexibility with the gas tanks I'd like to be able to have them outside the fridge. With where it's placed right now, it'd be best if I could have the line come through the left side wall (left side as I'm facing the front of the fridge), probably toward the rear. Of course, I'm concerned about hitting refrigerant lines with the drill bit. Are there any known locations of lines on that side?
