Part number: MER-0000781089 is a new, unused Genuine Mercedes fuel injection pressure regulator. Fuel Injectors require a set amount of fuel pressure to ensure they can spray a fine mist of fuel into the engine cylinder. As the engine accelerates more fuel is sprayed into the cylinder by spraying for a longer period of time. The fuel injection pressure regulator is designed to maintain a set fuel pressure (between 25 and 60 lbs.) no matter if you are idling or accelerating.
