Erroneous info. The check valve is just that, a check valve. Prevents fuel
bleeding out of the pressurizes system and back into the tank. Pressure
regulator does the pressure regulating. With this system, noisy pumps are
generally caused by repeatedly running them low on fuel, nasty stuff in the
screen, old age, and bad luck. HTH, John
