The 4 Port Fuel Pressure Regulators are designed for use with Mallory’s Comp Pump 250 and 500 Series of Electric Fuel Pumps in all out racing applications to regulate fuel pressure between high pressure fuel pumps and carburetors. It has four outlet ports and the least possible restriction to flow fuel. This style of regulator features a fully machined housing from 6061-T6 aluminum billet with four outlet ports and high flow fuel passages so that the racer no longer needs to be burdened with fuel logs and multiple fuel pressure regulators. These features, combined with the quick acting diaphragm assembly, make this style of regulator the most efficient regulator of its kind on the market today. A mounting bracket is provided to allow quick and easy mounting on the intake manifold.
