Default EJ20K vacuum line?

So,

I want to install a boost gauge on my completely stock EJ20K.

Looking at the intake seems like I have 3 options to put the "T":



1-) The line thast goes to the boost controller?

2-) The line that goes to the BPV (much wider hose than the hose that comes with the gauge and it would be too big for the "T" as well)

3-) Don't know where this hose goes to?

What would you guys recommend? Where will the reading be much mor accurate and avoid any issue on my car?

Isn't no. 1 the line that goes to the MAP sensor? Anyway, the line you want to use is the one that goes to the MAP sensor.

The line to the stock boost controller should come off the turbo outlet nipple which never sees any vacuum.

So #1 goes to the MAP sensor? If so, then should I "t" the line from that one?

Sounds like you've got the plumbing sorted out. As for the Glow Shift gauges you get what you pay for. I provided feedback under the product review forums on these gauges. I bought these for my '93 GF8 Lemons/Chumpcar and they were junk. They are inexpensive for a reason.

i would (and have had to) replace all the hoses .. chances are when you remove it it will be so tough that it will snap and you won't be able to get the T in
