Default Vacume Line Diagram

I would like a diagram of the vacume lines in my 1985 corvette. I have the 1985 Shop Manual but couldn't find a vacume diagram in it. If it is there give me the page number please. I would like to replace those 20 year old lines. No one has this?

I am not aware of a vacuum line schematic like there is for the wiring. There is a pretty good start of one pasted to the core support under the hood. The FSM should show the vacuum hose routing for each of the systems in the part of the manual that covers that particular system. Lastly, if you replace them one at a time, you should be OK.

RACE ON!!!

There should be a diagram pasted onto your radiator, from the factory, unless it was removed for some reason.

Anyway, here is a diagram I had clipped onto my computer.
I may have gotten it from this forum, I don't know.
