Below the carb. Its been just hanging since i got the car and i put a screw in it to stop any vacuum it was doing idk if i did that right or not where does it hook up?
heres some pics.




As you can see it has a smaller fitting in it thats held in by electrical tape and the fitting is threaded..

The owner before me has had alot of these cars but he said he could never get it to idle correctly which explains the random unhooked vaccum lines ive found.. So any help would be appreciated.. or possibly if someone has a diagram of all the vacuum lines ide be forever greatful.

 

Find a bolt that just barely fits into the hose, so you actually have to screw it into the hose. Coat it up with silicone, then screw it in. What you have there now is not up to the task, and I'd hate to see some of that hardware get sucked into the motor.

Are emissions tests required in your area? If not, then check out the FAQ section/"rats nest removal". This will remove about 90% of the BS under the hood. I currently have two vac lines on my car. One to the brake booster, and one to the vac advance modules. I like it simple.

 

Mine is the same as Kentetsu's. Two vaccuum lines and thats it.
Its all a very simple straight forward process. All your really doing is unbolting stuff and blocking off ports here and there. It really does clean up under the hood quite a bit.
