The Vacuum Control Valve & Solenoid Valves are two valves that are connected via vacuum hose in the emissions control system as shown in the MM in Section "T" on pages 4-7. It's been too long for me to remember where these 2 items are mounted, or even what they look like since I began the conversion of my 1978 403 to a 455 several year ago. I'm almost ready for the CA. smog test and need to install these 2 valves. I do have both maintence manuals, but can not locate my Parts Manual. The Maintence Manual only has emission diagram schematics on the above pages but NO PHOTOS.
Is there a link to photos showing what these 2 valves look like and where they are mounted?
Thanks..........Stephen
