okay....I have an undercounter unit in a custom bar. I want the tap mounted on the bar about 5-6 feet away. I am leaving about 3-3 1/2" space from kegerator to counter top to run hoses. I know that I need to set up a fan cooling system all the way to the tap. I have read many threads, but I want to make sure I have everything correct. So forgive me, I NEED HELP!

I have a double faucet tower that is 3" in diameter. Is a 2 1/2" hole big enough to route everything, or will I actually have to cut a 3" hole in the unit and counter top?? I planned on only a 2 1/2" cut.

Now, the cooling system: beer line running to tap along side a 1" flex PVC or clear vinyl hose connected to a fan in the kegerator. Around that, a 2" flex PVC hose for return flow. Will a 2" outer hose be big enough or do I need 2 1/2" to allow good return air flow?? Wrapped around the outer hose is foam/rubber insulation........

Now for the fan: 12V A/C or D/C?? How many CFM's?? Blower or PC fan??

Any help is greatly appreciated!!!!
