I will be using the very rear nipple on intake manifold (factory BOV vacuum line) to connect my new Tial 50mm BOV. I have read in some places it is best to have just one line running to the BOV without tapping into it. I am thinking of T piecing into this line and connecting my boost gauge to it. Is this a bad idea? If I should not do this, where else can I connect my boost gauge to on the intake manifold?

run two separate ones.

And where can I connect my boost gauge line then? The next nipple over?
