A fuel pressure regulator includes a housing having a housing bore and a housing inlet; a piston located within the housing bore such that the piston and the housing bore define an accumulation chamber and such that the piston moves between a first piston position where the accumulation chamber is minimized in volume and a second piston position where the accumulation chamber is maximized in volume, the piston having a piston bore with a piston inlet and a piston outlet and a valve seat defined therebetween; a piston spring which biases the piston toward the first piston position; a valve closure which moves between a seated position which prevents fluid communication from the piston inlet to the piston outlet and an unseated position which provides fluid communication from the piston inlet to the piston outlet; and a valve closure spring which biases the valve closure toward the seated position.
