63 vacuum diagram

I've got a 1963 Custom Sport Coupe, 394 ultra-high compression, nearly complete. It only has 57k miles on it, but it sat for a very long time before I got ahold of it. The previous couple of owners have had their go at it to get it running and driving and I'm trying to get everything running and driving better.

I've been looking for reliable diagrams for all the vacuum lines under the hood. Does anyone have reference material they recommend that might have it? I'm looking for how they did it from the factory but would settle for what others might be doing to get everything working. I have the 63 service manual as well as the parts catalogs, but nothing in those seems complete. just a little bit of the dash stuff or trunk latch.

Get one of these. Get a paper original, not a reprint or CD. There were no electronic originals, so any new one is a scan of an original and details usually get lost in that process. There are at least half a dozen originals on ebay right now, including an NOS one still in the box.

I've got that exact one. The only thing I can find vacuum wise is some of the dash stuff and the trunk latch. Am I missing stuff? The wife complains that I'm blind, all the time.

You're not blind. you're just looking for something that isn't there.
The only vacuum lines under the hood go to the power brakes, The "dash stuff " (the HVAC system) and the power operated trunk, if you have one.



Almost forgot, one line to the PCV valve and a line from the carb to the distributor for vacuum advance.

These are exactly what I am looking for, thank you. Are these out of the parts catalogs?
