2.7t Boost gauge issues

[andya143]

I installed a glowshift manual boost gauge on my car and it will only read the vacuum pressure not the boost. I have no idea why not. any ideas?

Also would anyone know where the fuel pressure regulator is located on the 2.7t engine? I've read the best place to tap into is the line before that.

did you install it after a check valve? Where did you splice in?

[andya143]

idk about the check valve. I spliced in on a vacuum line that runs into the top of what I would assume is the intake manifold.
