the fuel pressure dampener dampens the pulses coming into the fuel rail from the fuel pump so it doesn't surge really bad due to the pump. the fuel pressure regulator is on the outlet side of the rail and it regulates how much pressure is in the fuel rail at all times and lets the rest of the fuel go back to the fuel tank once the pressure is met.
