I broke what I believe is the diverter valve for my air pump. Well, smog check is comming up, and I don't remember how it hooks up. There are four tubes, and one vaccum hook up. I know that one pipe comes from the pump, and two others go to the exhaust. What does the other one go to? and where does the vaccum come from?

OKay

one Goes to each manifold Air injector Bank
One goes to the pump
and The other Goes to the Cat.

The Vaccum line comes from the carb ViA a temp actuated vaccum swich, PLugged into a ported vaccum source ( i belive )

Nothing goes to the cat. Too early. Thanks anyway.

 

anybody? Bort? Vader? Anyone?

 

The other one is the exhaust/bypass line and goes to the air pump muffler or air cleaner. What do you mean one does not go to the cat? Two go to the manifolds, one to the cat, one is the inlet, and the other is the bypass exhaust.

I have an '82, and it doesn't have a tube going to the cat.
Or is it supose to have one? I thought that they started that in '84? It didn't have one when I took it off. Come to think of it, the cat didn't have a tube on it.
