Never claimed to be very smart but how does this work if the pressure isn't regulated before it goes into the rails?

the regulator releases at the set pressure so the whole input line from the pump to the end is the same pressure,,Its simple as soon as the pressure in the line reaches the set pressure the reg dumps the fuel back to the tank, but the input line has constant pressure

Just so you know, to fine tune the fuel pressure:
Be sure the to adjust it while the car is idling but take the reference vacuum line off.
That's your static pressure, and that's the pressure you'll want to adjust for.
