I have searched everywhere and have yet to come across a vacuum diagram for a B18B1. It came out of a 97 Integra and I need help with locating a couple of the vacuum lines. Any help?

 

No one? This is something that should be a sticky.

 

 

Thanks a lot. A little confused though, this shows 2 lines coming off the front of the IM. Mine only has one vacuum spot on the front and its used correctly. But my fuel pressure regulator has no vacuum hose hooked to it and i dont know where to take it.

 

well i got the picture off of the 94-97 acura integra FSM so idk what to tell you...

 

I connected the fuel pressure regulator to a capped of port on the back of the IM and it brought my idle down significantly and way less reving going on. I also noticed the CAI has no line ran to it. I believe it connects to the port on the back of the valve cover correct?

 

that's good.

the CAI doesn't have to be connected to the valve cover. you can put a breather filter on the valve cover and cap off the port on the CAI.
but yea, that's where it originally goes.

 

Thought so but wasnt positive. Where do you get a breather filter? I think there must be some kind of vacuum leak somewhere...my idle actually seems a little low and it still revs a little, just not nearly as bad as before. But the anti freeze hose leaking like it is might be a possible solution though. Air going though the lines.

 

Ok. One more question....what is a normal fuel pressure while at idle?

 

breather filters are on ebay, auto parts stores, walmart probably, etc. lol

the leak in the antifreeze may have been letting air in. wait and find out.

FSM says to disconnect the vacuum line from the fuel pressure regulator, and then start the engine and let it idle. Then pinch that vacuum line closed.

says 40-47 PSI
