Does anyone have a vacuum diagram. I'm installing the original Rochester carburetor and want to make sure I set up the vacuum lines correctly. The car has Air, PB, and vacuum trunk release.
Thanks,
Bob

I took a look through the CSM and there isn't a vac routing diagram for the carb. Then I started thinking that the only thing that hooks to the carb vacuum wise is the distributor, if I'm not mistaken. All other accessories and items requiring vacuum gets the vacuum from a fitting on the manifold.
The brake booster hooks to a large fitting in the rear of the manifold. I'm haven't unwrapped my car to take a look, but I pretty sure there is only one large vac fitting. The A/C lines and vac-tanks hook up to smaller fittings or t-fittings depending on the accessories the car has. There is a diagram of the A/C vac-system in the CSM.

Bob,
I looked through my assembly manual and it shows one line going to the carb. Not sure if it shows everything for the carb. It does show the routing of all of the vacuum lines for accessories. Let me know if you want to borrow the manual.

Thanks,
Bob Bob: In the CSM under the heating section #14, check page #; 14-8, and then for A/C cars check page #; 14-76. If you have a vacuum operated trunk latch, the diagram for that is in section 12 on page #; 12-121. As far as the carb is concerned, there is one port on the back of the carb facing the firewall that goes to the distributor vacuum advance. If you did away with the vacuum advance then that port is plugged. The rest of the vacuum asseccories get their vacuum off the manifold and the pages above show that. |
