most of the vac lines are on the driver's side of the engine. Start from the power brake booster (that big black can on the firewall that's holding the master cylinder for the brakes) and trace along its big rubber hose. You will find a black vacuum distribution fitting. The point is to do a couple things.

One - any line that pulls off its fitting easily needs to be replaced. They should not pull off easy. They are either dryrotted or they were replaced before using the wrong size hose.

Two - bend a line around your finger. Any line with little cracks in it should be replaced even though it may not be leaking at the present time.

An easy way to do this is to go to an old-line auto parts store and ask the counterperson to come out and look at your car's vacuum lines and sell you a couple feet of each size so you can replace them. The better counterpersons can usually tell what size lines you have by looking and maybe disconnecting 1 or 2. Also, you may have some lines that have fittings on the ends. They will be obvious. Be sure to pull those lines to see what sizes you will need. Usually one "assortment" pack of fittings is more than enough. A fitting is just a little rubber tube - the vac hose slides onto the fitting nipple and then the fitting slides onto the engine somewhere - onto a vacuum fitting that is larger or smaller than your vacuum hose's diameter.

Then you go home and replace lines one by one. All you'll need is a pair of scissors. However, it might help to have an auto trim removal tool to help get the stubborn lines off. a set like this is OK:

I have one like this, you should be able to find it at a local NAPA (it might have higher price though)

Be sure not to bust any of the vac nipples (mostly they are plastic nowadays). The tool will help you avoid breaking nipples.

Good luck
