Radium Engineering DMR Fuel Pressure Regulator

Fits: 8th Gen Honda Civic

The Direct Mount Regulator (DMR) is the perfect solution for simplifying a high-flow fuel injection system. It's unique swivel inlet fitting adapts directly to the fuel rail eliminating external mounting and additional plumbing.

The DMR uses the same internals as the popular Radium Engineering MPR (Multi-Pump Regulator). This means it carries over the ability to change the orifice to match the regulator to the pump flow.

INSTALLATION NOTES: 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.

The 1:1 vacuum reference high-flow design has been tested to regulate over 1,400 liters per hour.  Furthermore, with the addition of interchangeable return orifices, the DMR can be used in ANY horsepower output EFI system imaginable and is compatible with all gasoline and ethanol blends of fuel.

DMR compatibility with fuel rails: Your fuel rail must have an available port with compatible threads. Furthermore, you need to have about 2.5" of free space off the end of the rail.
