Can fuel pressure be measured at the schrader valve on the fuel rail or do you need to connect guage inline if so which line and where?
Am installing adjustable Kirban reg and 255lph fuel pump.

Fuel pressure can be measured at the inlet to the fuel rail, and this is easiest because of the flexible hose.

However you want to be measuring differential pressure between the fuel rail and manifold so use a differential pressure device rather than guage pressure. Your pressure regulator works this way, it controls the differential (thats why it has a connection to manifold vaccuum).

I just fitted a guage in the flexible hose part of the fuel line (on the passenger side shocker tower). If you can get a guage with a schrader valve fitting it will be far easier though.
