Hey guys, I am installing a 1980 928 engine, which I did not remove, and I am having trouble connecting some vacuum lines. Does anyone have a vacuum diagram??
If not, can anyone tell me where the thin metal vacuum tube connects to? The one that is bolted to the front of the intake manifold, runs alongside the body and ends up near the firewall. What does this connect to??
Also, where does the vacuum advance for the ditributor connect to?
Thank you in advance!!

Mike
