Adjustable diaphragm lets you set fuel pressure while the Holley jet inside allows you to reduce idle fuel pressure without affecting operating pressure. Due to fuel pump variations, the jet is not included. The fuel pump relief valve features a stainless steel seat and bronze popitt valve for maximum resistance to corrosion.
