Don't do this. This is incorrect. The fuel pressure input is supposed to be from the output side of the fuel pressure regulator not the input side. Go to the next album (Q4 2006, section 2) for the correct installation of the differential sensor.
Did some assembly prep of the manifold pressure - fuel pressure differential gague system. The fuel conneciton side will probably change as the fuel system shakes out. I really wan to replace those banjo hose barb fittings on the fuel pressure regulator with soem sort of proper AN fitting.
