Okay i found a broken vacuum line on the passenger side of the motor. It is pink/peach in color. It is rapped with the Red and Black vacuum lines that go to the canister on that side.

I have no idea what it goes to though. I havent found a nipple or hose to put it in and the diagram says Air B.

Can someone help me find the correct location for this line.

Thank you.

 

well i finally found it. It is the valve that is on the smog pump lines to the exhaust. Theres a valve about half way back on the motor. And the nipple is on the bottom of the valve where you cant see it.

 

Glad you found it. I checked mine after I read your query and I was about to tell you where to route to and connect it. Glad you solved this issue with your truck.
