Hey, forgive me for my lack of knowledge, but I was trying to install an Edelbrock Performer RPM Intake manifold on my 89 GT (before I got deployed). I need some help with where to install the vacuum tubes. I took on the job after helping a buddy on his 87 GT and felt confident that I would be able to do it. All in all it isnt hard, but None of the vacuum lines match up to the stock plenum and that is just about all I have left to do. Is there somewhere I can get a picture. diagram, or tech article on where they are supposed to go. The instructions from Edelbrock are pretty vague. Feel like an idiot asking such a simple question. Thanks for your patience.
