Use 4mm silicone lines, what ever color you like. Buy a 10 foot length to be sure to have enough. Remove the old lines one at a time, cut a new piece the same length or slightly longer, replace before you forget how the old line was routed.
Don't mean to hijack, but about 10 feet should suffice when replacing lines for a 4-cylinder as well, right? And how about coolant lines, what's a good size for them?
The car may only require 6 or 7 feet of vacuum line. Ten feet is obviously more than needed but you won't have to worry of running short even if you mess up when cutting the long line last and cutting it too short.
There's such a rats nest of hoses back by the firewall that I can't imagine a diagram would do a whole lot of good. I bought a length of standard rubber hose at NAPA and just replaced them all one afternoon, one by one. A lot of the ones by the firewall are pretty short, and not all that easy to get to.
Kochiha, The coolant lines are all different sizes, and molded in weird shapes to fit around various bits in the engine compartment. It's best to stick with hoses that are made for your car.
I just need to make sure I get all the hoses.
The car idles erratically and stalls sometimes.
Replaced plugs, DICs, and CPS, so vacuum lines are next on the list.
That's why I'm trying to ensure I get them ALL

I'll figure out something else to do with the rest if necessary. Cost might be a factor, though; I'm going to shop around while the weather's still nice and Illinois-style crappy, then see if it's better to be frugal or be cautious.
Amazon sells the silicone lines. I would also replace the plastic PVC valve, its most likely cooked. I moved mine away from the original location on top of the TB, towards the fire wall and away from the heat. Check all air/vacuum hoses around the throttle body area. I had one that had collapsed.
