82 Blazer Vacuum Diagram

[Chris Ziemer]

Hi all, I’ve looked everywhere. Been to half a dozen smog shops and called the CA BAR.
Need a diagram for a 1982 Blazer, 350, CA vehicle, auto trans, light duty (light duty has an EGR, heavy does not).

My stickers are long gone.

I’m close, but not quite there. I know the EGR and EFE TVS units open different ports at different times, providing vacuum at different times. Hence the need for diagrams.

Any help is much appreciated!

Well I finally found it! Spoke to a State BAR guy, who went to his friends shop to send me a picture. Super helpful. Keep in mind, they were changing schematics every year for quite a while. I believe the enclosed diagram is only for 1982, as described.

Yeah, and people fear EFI for being "too complicated". Nothing cleaned up my engine bay more than getting rid of the hose spaghetti.
