Radium Engineering DMR Fuel Pressure Regulator OEM 11mm Bore 39mm Spacing (Green)
The Direct Mount Regulator (DMR) is the perfect solution for simplifying a high-flow fuel injection system. This variation can be used with some OEM fuel rails to replace the factory regulator. The included adapter mates to an 11mm bore and M6 bolt holes that are symmetrically spaced 39mm apart. Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability. See the installation instructions for more details. Either of the lower two opposing -6AN ORB ports can be used for the return line. Using the included fittings, simply install the 6AN male into the port that points in the ideal direction and install the plug into the remaining port. Fuel pressure is dialed in using the preload set screw on top.
Note: While the DMR will properly secure to the these OEM fuel rails, compatibility has NOT been verified when installed with the intake manifold on the engine. In some cases, there will be an interference preventing the use of the DMR. As an example, this adapter will fit onto the Mitsubishi EVOX 4B11T fuel rail, but it interferes with the MIVEC solenoid. Reference the dimensions below to determine if the DMR can physically reside in your specific application.
This architecture is common to the following engines:
Toyota 2JZ-GTE (not compatible with OEM intake manifold/throttle body)
Saab 9-2X Aero 2.0L
Subaru EJ20 GDA WRX
Mazda MX-5 BP
