'83 Vacuum Line

[cornholio]

I'm installing a new to me carb on my '83 pickup, my previous carb had the idle up diaphragm removed, now I have it back, but not even my FSM will tell me where I'm supposed to hook the vacuum line to. About an hour of searching and looking at the same diagram over and over has yielded nothing.

Can anyone help me out? Greatly appreciated.

It's a CA 4X4, so two canisters. I've been staring at all those diagrams since 4:30 this morning, none of them have what I need.

You had that funky system I had nobody could make sence of it.


See if you can get in touch with wristpin.

Need his number?

Everything I see says this particular diaphragm should hook up to AC stuff somehow, buuuut my truck never had AC, and it's on all the '83 CA trucks, but no one seems to know what the hell it is or where it goes.


I know where to find it, thanks crazy.

If it doesnt have ac just run that vaccum line in series / or loop it where it came from the start?

Granted this is coming from guys on Yotatech and such putting junkyard AC systems in their 1st gen pickups.
