I've just bought a used Offy regular dual manifold and have a pair of 94s to go on it. How am I going to hook up the manifold vacuum for my distributor? Engine is C59A.
Thanks, Marty.
 
If your running the front mounted dist there should be a a hole in the side of the manifold for direct vacuum. If no hole drill and tap a hole for a fitting. Walt
 
I am using an Offy regular dual. It has a vacuum fitting hole on the left side below the back carb. In my case it is capped since I am running a Mallory breakerless ignition. It has no vacuum advance.
 
Here is a picture so you can get a better idea of it's position.

If you have a crab type dist on there the vac passage is the 3rd hole on the back of the dist. Passage is in the block.Line was eliminated by ford on these dist. ken ct
 
Thanks 41ford1, that's what I wanted. I have'nt received the manifold yet, and the pics didn't show anything.
Cheers, Marty.
 
Even the crab dist has a pipe line from the manifold to a fitting on top of the timing cover that leads to the back of the dist. Walt
