Need a little help
Hi Guys. Its been a while. I have an 84 z28 HP and need a vacume diagram for under the hood. Some lines are missing and some are out of place. It has a 4 barrel quadrajet and all pollution controls. Also can I run it without the air pump and all that control it? Thanx in advance Ed

Check the FAQ forum for a thread about vacuum diagrams.
You can run without the A.I.R. pump as far as the engine is concerned, but not as far as the Feds are concerned.
