Unfortunately, all I have is the Chilton's Total Car Care manual for my car at the moment (I am VERY broke) and I need to find out how the vacuum hoses were set up. Can anyone provide a copy of a vacuum line diagram for this car?

 

When you get a few $$ pick up a Chassis Service Manual. Here's one that sold on ebay, I was watching it for a friend.

If your patient you should be able to get one for under $30 from a private party. There's a few businesses that sell them for more like $70ish and those are posted all the time.

Sorry, I don't have a 1972 but hopefully someone else does and can help you with the vacuum routing. John

 

Fortunately, there is not a whole lot of vac hose on these cars.
The most will be found hooking up the TCS solenoid.
Here is a thread with a diagram.

The modulator is at the tranny.

There is a thread mentioned at the end of how to bypass the TCS is it is broke.
The remaining hoses are pretty straight forward, like PCV and heater control, and gas tank vents.

 

Don't ferget the vaccum hoses behind the dash to the heater/ac controls. Yuk.
