Vac Advance Plumbing with air pump removed
I have removed the air pump and running a belt directly from Crank pulley to AC compressor (forget the Bando number but it's a perfect fit). No tensioner needed.
Anyway, does someone have a vacuum advance plumbing schematic that is simple and uses just the regulator and dump valve without all the other nonsense?
Thanks.

I have done this, and assuming you have Lucas ignition:
Greg
- remove the wires from the temp switch on the A bank rear water manifold and tape them up. This disables the 15 minute enrichment timer that you do not need.
- run a vac tube direct from the advance/retard capsule on the rear of the dizzy to the spigot under the A bank throttle body.
- remove (or tape off) all the other stuff with thin vac lines to it and all the little boxes.

Awesome. I had read somewhere that you needed the dump valve to prevent detonation if you floor the throttle while cruising.
I like your simple setup. I know my advance module is toast. It is next on the to do list after cooling system overhaul (nearly complete).
Thanks.

This one in the pic is is not connected to the adv/ret vac tubes at all.

One note of caution.....
At least one of the vacuum thingies, as I recall, is a redundant dump valve for the cruise control. Might wanna leave that one in place, if you have it.
I think cars prior to xxx-point were retrofitted as part of a recall. Cars after xxx-point had the valve fitted at production.
I can try to find the details (to augment my foggy memory) or you can simply look for a vacuum tie-in to the cruise control hoses/servo.
