Re: V8 vacuum routing diagram?

Many thanks for your prompt and clarifying response. The vac line routing and hose dimensions are most appreciated.

I recently rebuilt the Rochester carb using a specially ordered NAPA/Echlin kit. This was a multi-application kit for mid-Fifties cars that used this GM carb, including Cadillacs and Buicks, as well as senior Packards. Now some self-doubt is creeping in; did I use the proper lower and base gaskets to insure a proper vacuum path? I think I did, but when I get back to the car, that check valve port will be the first place I use my finger to check for both suck and sound. Luckily, the unused rebuild gaskets should still be boxed together and stored in the trunk of that car.
