if thats the line thats coming off the throttle body back to the throttle body... YES!

although ive seen people tap the line thats off the BOV. the throttle body is the best place to get an accurate reading from


added a pic of mine (from the factory)
hope that helps if yours is diferent

Is that the line that goes directly to the FPR? If so, it'll work, but not exactly correct. See here: https://www.evolutionm.net/forums/sh...ad.php?t=96614

Edit: Although, since you have just a boost gauge, it might be fine. Not sure what the FPS does under boost while the ECU keeps it closed for vacuum.

My factory optional boost guage that came from the dealer was tapped exactly like the image tokeone attached.

You should tap the vacuum line right off the intake manifold before FPR, it needs to be before the fuel pressure solenoid since you could get incorrect results from the solonoid.
Just like 4ce fed said . everyone I know who has tapped it after the FPR has incorrect psi values and did not know it until they went to the Dyno day and got psi readings several cars showed higher psi than they where actually making
