Hello folks,
I have a 1996 Buick Park Ave that I recently replaced the upper and lower intake gaskets, serpentine belt and alternator on. Im finally almost finished! I have the wiring harness completely hooked up and everything is finished except for one tube (Looks like a standard vacuum hose) that diverts from the rear of the wiring harness behind the cylinder head. I took the best photos that I could before I started and it looks to connect right under the first fuel line that goes into the fuel rail. With that there is a hole (circular hole about 13mm) that is on the back of the upper plastic intake where something should definitely go. Im wondering if there is a specific piece to combine the two and if there is, what would it be called and where could I find one? Ive looked everywhere and have found nothing.
Any help would be greatly appreciated,
Thanks!
Andy

Can you post a picture?

Brake booster line.

Mike is right, the tube comes out of the wiring harness, and goes into the back of the upper intake, right where the big brake booster hose goes.
Inspect the soft part of that hose, it turns to a hard line where it goes into the wiring harness, so if it is dry-rotted it is easy to replace, on my 96' Park Ave almost all EVAP hoses, and connectors had to be replaced.
If you decide to check/replace yours I'll try to help you find them all, there are quite a few that can dry-rot over time.
