Vacuum line location- 5.2 V8 ZJ
Had the stealership do some intake work for me. Went to double check it because of my vacuum leak (engine idles from 800 to 1100) and this is what I see. Can't find any good diagrams. Any idea where this line connects to? The two bottom ends
connect to the intake manifold, but I can't find where this tore off, or was just left disconnected. Thanks guys.

Old fart with a wrench
IDK, but looking at your pic, there is a check valve or filter in that line. It may be the vacuum supply for the heater controls. Is it sucking air? It may be it wasn't attached because your new engine didn't have a fitting for it.
