    It's on the emissions sticker on the underside of the hood or on the radiator support.

    One things for sure, there's a bazillion vacuum lines on these cars!

    I've been replacing some of the primary lines on mine, and all the rubber fuel lines.

    It has no vacuum hoses compared to the oldsmobile 307 in 1986-1990 broughams. Now that is a confusing motor to figure out with messed up vacuum hoses.

    You could always go to AutoZone's web site to find vacuum diagrams. They should have what you are looking for, or go to your local Chevy dealer, not sure if your local Cadillac dealer's repair department would help you out.
