Where is the brake booster?

[Haase]

hey guys, im working on finishing up my turbo install on my 420A (I apologize if this thread is in the wrong catagory) and so i need to tap into my break booster line to run some vac lines from it to go to my boost guage and FMU. problem being is i have NOOOOOOOOO idea where it is... so if anyone could explain where it is i would really appreciate it cause i really want to get this done and this is the only thing holding me up. thanks!

You shouldn't tap into your brake booster line for anything. Usually people tap into the line from the FPR to the intake manifold for the boost gauge.

He can use the brake booster, as long as it's tapped before the check valve so it can see boost.

The brake booster on a 420a is behind the battery under the brake fluid reservoir. There is a fat hose in the middle of the intake that u can trace back if u still cant find it.

If you don't know what the brake booster is you probably shouldn't be tapping into it unless someone can show you exactly how to do it.
