What should the pressure be on a Ford returnless?

Take the 40 psi on the PID, add to that the 5 psi of absolute pressure for a sum of 45 psi. Then subtract from that sum the 15 psi that your gauge is referenced to (at sea level). You should be left with 30 psi. If the FRP sensor and your gauge are both properly calibrated, they will match that 30 psi.

How does the fuel pressure regulator work on a Ford?

How is circuit 3 connected to the fuel pump?

Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate. Before this voltage reaches the fuel pump, it has to go through the fuel pump Inertia Switch first. If the Inertia Switch has been tripped, it will ‘open’ the circuit and the voltage will not reach the fuel pump.
