Radium Engineering Direct Mount Fuel Pressure Regulators

The Radium Engineering Direct Mount Regulator (DMR) is a compact high performance adjustable EFI fuel pressure regulator designed with a unique highly versatile mounting system. It can be mounted directly to a compatible fuel rail port using the included 360 degree swiveling adapter, or mounted remotely away from the fuel rail. The compact size fits in areas with limited space without sacrificing performance. This regulator is safe to use with all gasoline and ethanol blends of fuel. The main inlet port on the regulator is female threaded for 6 AN ORB. A swiveling double-ended adapter is included with the kit that allows the regulator to be used in any compatible 8 AN ORB fuel rail port, such as those found on Radium Engineering fuel rails. The return port on the bottom is threaded for 6 AN ORB. The provided 90-degree 6 AN male fuel return fitting can swivel 360 degrees, permitting a multitude of mounting configurations. Other adapter fittings can be installed in the return port if needed (sold separately). Unlike the previous generation, this DMR has two 1/8 in. NPT side port locations that can be used with a pressure gauge, transducer, temperature probe, etc. Two 1/8 in. NPT plugs are provided. Fuel pressure is dialed in using the preloaded set screw on top of the regulator. Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. This permits the DMR to be used with practically any horsepower engine. This added precision will resist diaphragm flutter and optimize pressure stability. This design has been tested to regulate over 1,200 liters per hour.
