Default please check my vacuum line locations

ok i did a search and found a lot of helpful info. now i am about to run all my vacuum lines, and want to double check if i am doing it right, because by following instructions and what has been posted on here i have my vacuum lines being sourced at the #3 manifold( also need to verify this is the one i need to Tee into, so please let me know if what i have in the pic is correct)

basically i came up with this vacuum line being my only one i tee into if i am following the instructions correctly, i use this line for my BOV, boost gauge, Autronic ECU(for MAP), and then to boost solenoid to control wastegate.

also i was wondering what this vacuum line is and do i use this one for anything?


k, last question...for now basically on my air filter pipe there is one hose barb, and then i have some plastic tees to Tee into a hose coming off it, but my question is do all of my PCV lines go into this one? maybe i am confused on what PCV lines are but the ones i am referring to are the 3 hoses you would normally connect to an intake, one located on pass side, one drivers, and one next to the throttle body.

thanks a ton for the help. im almost there!!

Ben

You might want to t your ecu off the throttle body vacuum line as the invididual cylinder vacuum might be a little jumpy. It would be a good idea the have that one on its own vacuum source. Otherwise everything looks good.

If your piping to the charge pipe has receptacles for you pcv lines (and yes, those are the pcv lines) run them there. If you dont then run a catch can. Cool?

thanks for the help, is the throttle body vacuum line the one in the second pic i posted? or where is that located? thanks again

Ben

oh yea, and is it fine to just use vacuum line for all those, i mean would i benefit from a harder wall hose at all? i have 5/32" vacuum line and i also have 3/16" fuel line, the 3/16" in fuel line came with my Blitz BOV and i was wondering if maybe they know something i dont and it is better to use fuel line cause it is more rigid??

Second picture is the throttle body vacuum line. I bought just regular vacuum line at like pep boys and it's been fine for over a year now.

PHAT suby: i beg to differ i belive that line (in the second pic) is for the fuel tank purg line the hooks up to a valve on the fender.
If that is the same line i am thinking of. there are only two ports on a stock subaru (on my 99RS) you can tee into one is the FPR the other is on top of the manifold. Correct me if i am wrong?

I believe that the one in the second pic is the vacuum source on top of the manifold you referred too. It's right in front of the throttlebody

maybe it is used for the idle air control or something, but it is fine for the ECU to be hooked up to it even when the boost gauge gets funky off of it?

my damn laptop wont connect to my ecu otherwise i could tell you if its all functioning properly.

thanks for the help

I currently have my Link+ connected to the vacuum line in the second picture. Boost gauge is connected to the port that used to have the cruise control plugged into. Both are working fine.

(edit)...so far...
