The Radium Direct Mount Regulator (DMR) is a compact high peformance 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.

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. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability. See the installation instructions for more details.


1. Compatible with all gasoline and ethanol blends of fuel. 
2. For a 3AN vacuum signal adapter fitting.
3. It is not uncommon for pressure to bleed down when the fuel pump is turned off. This is not a sign of a malfunctioning regulator.
