Magnuson fuel port size ? Need to adapt a fuel pressure gauge to Magnuson TVS1900 fuel manifold.
Anyone here know the gauge port size and fastener style or series needed to fit the fuel regulator manifold ?
Symptoms may indicate that fuel pressure is not tracking with manifold pressure.
Both fuel pumps are confrimed running, fuel tank is full, fuel filter in use less than one hour... idle and cruise at 14.7 - 15.0 AFR
BE and PE fail to lower AFR with rising MAP... vehicle is not driveable, and is not near parts store., need to obtain proper fittings to monitor fuel pressure.

edit:
port is 9/16-18 straight thread, with O-ring, aka "-6ORB"
need -6 ORB to 1/8 female pipe taper.
.
update:
... Gauge confirms fuel rail pressure, static, key on: 52 PSI
.................................................. .......engine idle, 48 PSI
Blip throttle, rail pressure spikes to 54 PSI
On road test, we can maintain 6 pounds boost up to 6200 rpm, AFR 11.4
Plenty fuel on tap.
