wondering what size vacuum tubing would be best to use to replace all the vacuum lines on my 97 cherokee 4.0l 6 cylinder 4x4 with manual transmission.

I hate the 22 year old plastic stuff in my XJ. I don't know what size it is but when I have to replace any of it, I get metal brake line and bend it to fit where it needs to go. I had a bad problem with the line going to my MAP sensor. That plastic stuff that comes in a small roll from the parts store, it would get warm and the vacuum would suck the line closed. Now, I don't have to worry about that ever again.

Check out siliconeintakes.com they have vacuum kits or you can order size you want. Rubber vacuum hose will collapse over time. Silicon hose doesn't.
