Hey guys, sorry if this is the wrong section to post this. I'm all done with the aem meth/water injection kit expect tapping into the vacuum line. I'm not sure which one to connect too. I wanted to connect to the one on top but that is where the boost gauge is and aem stats not to use that hose. I took a picture from another post. Can I use either of these or what do you recommend?

Here are the exact diretions: Find a location after the throttle plate to tap into your manifold pressure (boost). DO NOT hook up to the pressure at the turbocharger or at your boost controller. It must be after (downstream of) the throttle plate. Use the supplied hose and tee" if needed.
he supplied hose and ee

 

someones got to know...

 

I DO I DO

Tap into the line where the BOV is tapped into, any vacuum source will do, but thats where I tapped mine

 

got a picture?

 

all the blue lines are vaccum, if you look at the top left of this pic you will see a blue vacuum line that is T'd off into a black tube that goes from my intake to my valve cover area, just tap into there

 

does it matter that my boost controller is connected there?

 

No, I have my Boost gauge tapped into that as well, and I will be tapping my new EBC into the same line

 

Your vacuum line is a connected system, meaning each item will see the same vacuum no matter which port it's connected to.

Your w/g, bov, fpr, b.controller, etc will all see the same amount of vacuum/boost pressure.

Otherwise nothing would work..lol.

 

done everythings working, just need to clean everything up now...

 

What engine mgt? If AEM get rid of some of the junk.
