On cars with the throttle pressure regulator, the banjo fitting should be removed from the fuel distributor and connected to the gauge set on the outlet side--between the outlet and the hose to the cpr. If you still get low system pressure after correctly hooking up the gauge set, it's possible the pressure relief valve, near the inlet of the fuel distributor, is not functioning properly and allowing fuel to return to the tank at a lower pressure than spec.
