gage line into this loop I was concerned about air flow to the boost gage affecting the pressure in the relatively small loop line. I determined that there is not an air bleed from the boost gage, and virtually no flow. My car idles great and the fuel pressure is perfect with this connection, but I would not make just any connection here. This connection does free up the balance tube nipple for the boost controller connection that it uses to determine your manifold boost.
