I need some help guys. I have a 1977 GMC K10, 350V-8, Quadrajet. The truck has had a new painless wiring kit installed, new motor ..etc. The bad news is that I never took pics of the vacuum lines and threw away all of the old crusty ones. I can't figure out where the lines are supposed to go. I've looked at Haynes and Chelton. Both have horrible diagrams. Does anyone have access to the factory manuals? Anyone have a vacuum diagram for this type of truck?
