There's also pulses caused by the injectors. Each time an injector opens, there is a slight drop in fuel pressure. The Damper compensates for this temporary drop in pressure. It's basically a spring loaded device that keeps pressure up.

Where as the fuel pressure regulator releases fuel (back to the tank) when pressure is too high. It keeps the pressure down to a prescribed, safe level.

They work together to keep pressure even.
