Vacuum hose leaks

Where can I get a diagram for the vaccum hoses on a 94 Grand Cherokee
5.2 L. I am losing vacuum somewhere but don't know where. Thanks

On a vehicle that old, it might pay you in the long run to replace all the vacuum lines under the hood.

There's usually a diagram on a sticker under the hood somewhere, or even on the hood.

Or, just do a Google search; I did a quick one and there are lots of places that might have it.
