Sounds like several people have been in there over the years messing things up. There should be a vacuum hose routing diagram under the hood as part of the emissions decal. If that's gone, visit your local Ford Dealer. They might be able to download and print the diagram from Mitchell On Demand, if they subscribe to that service. If you're restoring this vehicle, get a factory shop manual. This is way better than the generic manual you're using. The manual is specific to your vehicle. It will cost a little more but worth it in my opinion for a restoration project. Try ebay for a good used one or Faxon Auto Literature. Faxon has a website and good quality shop manuals, both original and reprints. I've bought from them before. Hope that helps! Jim
