Re: car keeps failing smog

You're working on a Camaro but what year model?

This link might help you a little bit:

Photo 1 - That's the vapor canister.

Photo 2 - Can you tell where the other end of that line goes after the tee?

Photo 3 - That's the cruise control diaphragm. It's what pulls the throttle when the cruise control is engaged.

Photo 4 - That's the vacuum source for the cruise control and heater/AC controls (HVAC). That plastic tee is a one-way valve. It holds vacuum in one direction and allows vacuum in the other direction. The cruise control and HVAC controls are always connected to the tee on the opposite side of the engine. The unused nipple goes to the HVAC vacuum line; it should be coming through the firewall near the back of the engine.
