Default Boost gauge install

Where did you guys install your boost gauge? Meaning what did you hook the line too? I can't seem to get a reading on the gauge. It's an l-98 by the way.
Thanks

Let me add a blow off valve question too, is it supposed to be blowing air out at idle and close under accelration? I have that vacuum line hooked up to the second port on the back pass. side of the manifold. I have the boost gauge hooked up to the first port on the same side.
Thanks again

It hooks up to the vacuum port... virtusally anywhere on the intake will work fone, your vaccum for the bypass valve can also connect to the same vacuum port...

At idle it will blow are out the bypass valve...

I put a 4 way "T" on the line that goes to the fuel pressure regulator. One goes over to my sensor for boost gauge, one goes to the stock fuel regulator & the other goes to the FMU & also the boost bypass. Which is open until you hit zero vacuum, it then closes & all your boost starts to build.
