I am trying to get my vacuum lines all in the right place and I can't find a reference that shows the proper configuration? I even bought the 1968 Firebird/Tempest shop manual but it does not show the config. I have an all stock 1968 400 V8 with automatic transmission, power brakes/steering, 4bbl quadrajet. Does anyone know where I can see a picture or diagram that shows proper vacuum hose placement for my setup?
