Hey all. I'm putting a 1990 SD setup in my 1987 Monte SS. I didn't see any Camaro vacuum diagrams with a vacuum storage "ball", like in my Monte. Did any 1990 - 1992 TPI's come with these? If not, weren't they needed? Thanks everyone.

They came with all systems. I have a 92 and its under the drivers side by the evap canister and horns. They were used for the AC and heating. So when you went to wot you would still have vacuum to hold open the the doors in the ducting. Mnake sure you have the check valve installed with it.

Ok, thanks. I didn't see them in the schematics, so I wondered.

If you need a schematic I can email or post a picture of one.

No thanks. I'll look for a spot to bolt mine in where it fits. Thanks for the offer though.
