I can't seem to find a diagram for a 79 USA vacuum system and I could do with a better understanding of all the hoses I'm trying to put back in.

Anything will probably be helpful.

By the way my car has the EGR removed

Also check 928 classics website, and importantly- a member has posted tech specs onto google drive, if it covers 79 you'll want to have that!

I'm P/R bound in the near future- hoping for none of those spiders!!!!

Ok, so all the diagrams show two vacuum lines to the WUR, why does it have three?

Don't worry too much about the spiders unless you're planning on staying under a house in hills like the car did HAHA.

DOn't know what to think about three vacuum ports, can you post a pic? I only recall two on my euro. There's some additional explanatory info here:

The third one is the one I'm pointing at. The line on it goes to where I thought it went on the throttle body.

I'm seeing two fuel lines, one electrical bundle- and is that a broken wire in there(?), and two vacuum lines one cloth covered and one rubber.

The one your pointing at is supposed to provide WOT enrichment on RoW engines. Adds vacuum under the diaphragm/spring assembly inside the housing.

Unfortunately I don't remember exact placement on the TB.

I see your green ignition wire snaking through down there....I usually don't recommend pre-emptive, pre-failure part replacements but in that instance, I'd budget for and replace it. It'll help eliminate one frequent fault from the sorting out process to come once its running.

Plus, they only get more expensive as time goes on.
