    Does any one know where I can get a vacuum diagram for a 1990 suburban 350 TBI. I would like to run new lines. I bought the truck over six months and the vacuum situation is sad. Lines going in every direction, and golf tees in half of them (previous owner). Any help would be awesome.

    Do you have a vacuum diagram under your hood?

    Under the hood

    There isn't anything that resembles a vacuum diagram, I have yet to try a smog shop. I haven't had much time to get to that project. Thanks for the replies.
