Oil injector question.
 

I have redone everything in the engine compartment while installing my Haltech. I was wondering do the oil injectors just get hooked up to a normal vaccum source like the fuel pressure regulator does? And no one tell me to just run premix!;) Thanks for any help you can offer.

yeah it is just a regular vac(or boost source) source,,i am going through mine right now,,i replaced teh oil and vac lines,,they were all cracked to hell

Thanks that cleared up alot vuccum line headaches I was having, knowing that I went from a whole shit load of vaccum lines to about 5 that I now have to worry about.

Just use the stock vac line and spider, it connects to one of the three nipples on the firewall side of the plenum. New ones would be a good idea depending on cost.

On an 87 TII, the oil injectors are NOT hooked up to a vacuum source, but rather a clean air source. This is supplied by the larger nipple on the throttle body facing the firewall. It goes to a port in front of the throttle plates, which never has vacuum on it, only boost. I don't know what happens if there is vacuum on this line, I just know there is no vacuum on the stock system.

So as long as I connect it to where it origionally came off of it will be fine. Does it matter that I have all the other nipples on the throttle body blocked off?
