Needs Chevy Pickup Vacuum Diagram


The emissions label is under the hood. This will give you the vacuum diagram. I would need to know if it is a California or Federal model before I can get you the right diagram. The decal will tell you if the vehicle has California or Federal emissions.

If the decal is missing, you will need to go to the local public library. In the reference section they will have engine vacuum diagrams and you will be able to match one up to your engine.
