Review HOLLEY Vr Series Fuel Pressure Regulator 4-port Adjustable High

The Holley 12-864 VR Fuel Pressure Regulator 4-Port High is a high-performance fuel pressure regulator designed for applications requiring precise fuel pressure control. This regulator is part of Holley's Victor Series, which is known for its durability and ability to handle high fuel flow rates.

The 12-864 VR Fuel Pressure Regulator is a 4-port design, which means it has four separate fuel pressure outputs. This feature is ideal for multi-carburetor or multi-fuel system applications, where each carburetor or fuel system requires its own specific fuel pressure. The regulator allows you to set and maintain the exact fuel pressure for each system, ensuring optimal engine performance.

The regulator body is made of heavy-duty brass, providing excellent heat dissipation and resistance to corrosion. It features a high-flow, 3/8-inch NPT inlet and four 1/4-inch NPT outlets. The inlet is equipped with a 30-micron filter, which helps to remove any contaminants from the fuel before it enters the regulator.

The regulator uses a vacuum-operated diaphragm to control fuel pressure. It features a 1/8-inch NPT vacuum connection, which allows you to adjust the fuel pressure by changing the vacuum pressure applied to the diaphragm. The regulator is also equipped with a 1/4-inch NPT adjustment port, which allows you to make fine-tune adjustments to the fuel pressure without removing the regulator from the system.

The Holley 12-864 VR Fuel Pressure Regulator 4-Port High is designed to handle high fuel flow rates and can maintain fuel pressure in applications with up to 100 psi maximum system pressure. It is suitable for use with gasoline, methanol, or nitrous oxide fuel systems.

Overall, the Holley 12-864 VR Fuel Pressure Regulator 4-Port High is a versatile and high-performance regulator that is ideal for applications where precise fuel pressure control is essential. Its heavy-duty construction, multiple fuel pressure outputs, and adjustability make it a popular choice among automotive enthusiasts and professional racers.
