Got the car cranked and now need some help with missing vaccum lines.

Ive been trying to get my car cranked for a solid week and finally did this morning. Some of you guys knew I was having problems after I had fixed a bunch of things on it. I thought it was flooding which is what happened. Im so excited to have it going again Anyway, I was going over the engine just checking for leaks and stuff and noticed some vaccuum lines were not hooked up right. One line is missing, although it was that way when I bought it. I took some pics of these in hope that someone can tell me where they go. Here is the pix. Any help is greatly appreciated.


Where does the hose outlined in red go? For right now I have it on the nipple that I have circled in red. Where should the vaccum line go that is circled in yellow? The hose that connects the metal lines under the BAC is cracked and dry rotted I havent replaced it as of yet...its the one circled in blue.....What kind of problems would it cause being cracked like that? Where does the Vaccum line go that I have outlined in yellow? It is the one that has the screw in the end of it in the pic.

red -- that is for the blow off valve
blue-- it might cause a big vuccum leak
yellow-- connect to your boost sensor

You should download the PDF of the fuel & emmissions section of the manual.

It's all there on page 5.

link to my copy of the manual

Thanks alot you two. So sure shot if that lines not connected that should make my boost gauge not work? The reason I ask is it was like that when I got the car and the gauge would work off and on. Weird. Thanks for all the help youve been lately man. Later .

Yup, I moved the line I had running from my boost pressure sensor and plugged it into the line that was capped. Boost gauge works again now lol. Thanks for all your help guys I appreciate it.

Hey Sureshot...how do I get the whole PDF file?
