It's been almost a year since I replaced my beer and gas lines in my kegerator (four taps and six gas lines, two are dedicated force-carb). When I rebuilt it after purchasing (it was set up for sankes, I use ball-lock cornies exclusively) I used the cheap vinyl tubing for both beer & gas. I'd like to switch to the eva-barrier for the tap lines, which I can get at Amazon; but I'd also like to switch to duotight/John Guest fittings for easier cleaning/switching out of connectors/lines. Has anyone out there done this? If you have, can you give me an idea of what I need to buy? My manifold has the removable barbs so I can connect directly to it. I use about 6' of 3/16"ID tubing for each tap, which works for me without foaming.
