ATQ (V6) vacuum line diagram needed

I've been searching for a vacuum line diagram for our Passat. The Haynes manual doesn't have it (I'm looking into buying a Bentley manual set). I'm reinstalling everything after fixing the leaking heater core hose o-rings, and I'm having difficulty figuring out how a couple of the long lines connect that seem to run on either side of the intake manifold.

I've reviewed the vacuum line replacement DIYs that are here, but they aren't giving me the information I need to sort out my lines.

Oh, and I replaced the hood back in May when I repaired the damage from m son hitting a deer. Unfortunately, I didn't take a picture of the label on the hood, and this replacement hood is for a 1.8T so it doesn't match our 2.8 V6.

TIA

So, I think I eventually sorted out where the lines go. One tied between the EGR valves off of the back of each cylinder head, another went to the drive unit at the front of the intake manifold, and the last one went to the vacuum pump. I still haven't found a diagram, yet. I am looking to buy a set of the Bentley manuals...I got away without them for a long time (we've had this Passat 10yrs now), but I don't want to hunt for this info on the next repair.

UPDATE 20241204: I have the Bentley repair manual set, now. I found a good-condition hardcover set :)
