okay if u are using ur air jet controller. that is the thing with three lines. this helps from flooding ur carb with gas. then ...

D goes to 7 on the intake manifold not the carb.

n 7 goes to D on the back of the carb.
also cap 8 on the manifold bottom pic

this is ur air jet controller n it needs to be hook up. NO FLOODING!!!!
Posted Image
A to 11
B to 10
C to 2

that should be everything, its better to use new vacuum lines so u know that none of ur lines are cracked. also on the manifold i made sure that the caps wouldnt come off by using small hose clamps instead of zip ties. just a better option to me. u can leave ur valves on but i was going for a cleaner look so i went with block of plates; u can make ur own but unless u make some thick ones ur better off buying the ones KAYMO has here. another thing is the base plate insulter on the carb make sure it has no cracks bcuz those are notorious for leaks. if ur on a budget>>>then silicone is ur best friend.coat it on both side like a skin just make sure u let it cure 24 hours.before use. other that that u shud be good. GOOD LUCK on anyone trying it out.

ps this is not for California bcuz of smog. unless u can find someone to do u a favor u will never pass. sorry.

any questions let me know il check from time to time here if not PM me.

So what about this method:

I purchased my 87 DX de-vacced already, and that line is glued on. The two vacuum lines on the dizzy are unplugged. #4 in phenams pic is blocked like DarkHand shows in another thread. What will this change? It used to be an SCCA Club Racer so I'm trying to figure out all the little things the previous owner did to my car.

Thread revival!  Another successful devac here.  I wanna thank everyone who posted on this thread, it was very helpful.  My car runs like a top now, which means I can turn the other one (98 Integra) into a race car :)  Thanx again guys, this thread is a life saver.

Just wondering if the connectors for the vac control boxes just get abandoned in the bay. Any great ideas on how to make them look decent? Anxious to see how this old 87 DX Auto will run once this is complete. THANKS!
