1969 - 472ci Vacuum Diagram

Looking for some guidance and hopefully a diagram to help me chase down some vacuum issues on my 69 hearse.

I had the Rochester Quadrajet rebuilt and have it back on the car. When it came apart there were a number of loose hoses which did not help with my reinstallation.

The carb has 3 ports:
1 large port on the back - connected to the brake booster
1 small port on the front passenger corner - connected to the choke
1 medium port on the front going to the vacuum advance
There is also one nipple on the rear passenger corner of the intake.

I KNOW my routing is wrong. There is a thermostatic vac switch on the front of the engine but I do not know which line should connect to it, to which port or to where each line would connect from the switch out into the car.

At current my HVAC does not work, nor does the parking brake. I am sure these are all related to vacuum lines being wonky.

Hoping someone can help me identify everything and get straightened out!

Thanks!

I searched my library, and all that I could find was the vacuum diagram for the 1974 model year Cadillac.

You have one coming up from the transmission and one coming up from the neutral safety switch the were either t with the brake booster or off a port in the intake. The distributor is off the front left the egr valve is normally big one off the front base. Not a lot on the 69.

Ed, if you recall, the air conditioning is supplied by the thermo vacuum valve located at the front of the engine. This valve has four ports exiting it, and one port feeds the valve. If you remember, you could get either the heater or the air conditioning working on my car, but you never could get them both working at the same time. The same applies to the vacuum parking brake release, which was activated by the neutral safety switch when the car was shifted into drive. That switch always leaked and never worked correctly. I believe that the 1969 Cadillac vacuum lines were among the most problematic components of my car's restoration.

Remember is was a problem
