    Hello, I am trying to clean up the rats nest of hoses in the engine compartment of my '83 K5. I am just curious what you have hooked up and what is the bare minimum to have hooked up to pass an emissions test, I am in AZ.

    I would follow the VECI on the radiator, but that one is for a 305 and there is now a 350 in there and not all of the components seem to match.

    Anyone have a vacuum diagram?
