Tubing question real quick

I went out and grabbed tubbing at my local homebrew store along with regulator and quick connects. I know which goes where and so on. I get the basics to it all but I was in a rush.
I got two kinds of tubing one clear and one braided. Now I remember him asking aboit distance between the keg and tank and I think I remember it being the braided but in all the rush today I do not remember if the braided goes to the co2 then in or the clear. Im confused with info given online only because I see colored tubing between the tank and keg.
Common sense would tell me braided but I'm not sure now. Odd how the simplest part of it has me thinking.

 

It doesn't matter, except the serving/beer line needs to be about 10 feet (no less) of 3/16" ID (no larger).

 

Usually the gas tube is 5/16 inside diameter and the liquid tube is 3/16 inside diameter

 

Thanks!! Makes sense now. Length and size....The clear is the longest and 3/16.

 

So from what I get from reading up just set it at 10-12 psi leave it on and forget about it?

 

That works great if the beer is cold (38-40*F).

What length lines are you using? What BobbyM said is true. You want to have at least 10ft of 3/16" beer line. I use 12ft.
