I posted earlier about rebuilding my carb, and possibly removing my intake. My 86 Chevy pick up has ALOT of vacuum lines on top of the intake. It seems overly excessive. Many T's with Vacuum lines going many places. My question is is there anyway to clean this up, or like eliminate some...im not exactly sure What I need Vacuum going to.

Ahhh... the snake pit. Most of those lines are used for the various emission components on your engine and they are all basically interconnected. If you live in California you will need all those to pass your emission checks every 2 years. (Unless you know someone willing to ... never mind) I'm not sure about other areas of the country.
You could partially de-smog the motor by disconnecting and plugging the lines to the various smog components but your performance increase would be minimal at best and possibly get worse.
If you are just concerned about the cosmetics of the engine compartment, I suggest rerouting, extending, and bundling the lines into looms. I plan to do this on my 84 Burb but it is a ways down on the to do list and I need to sit down and map it out.
Hope this helps.

Thanks, yes that helps some...I am goin to try and clean it up like you said. I live in Houston where we do have pretty strict emissions, but being an older truck, it is just like a visible look to see that you havent totally changed all the emission set up.
I think I will look at all the stuff there and redo it all with no hose, and T's and other fittings that need to be replaced, and then maybe use some sort of loom like you speak of.
Thanks.
