Radium Engineering Direct Mount Regulator (DMR) 8AN ORB - Green

The Radium Engineering Direct Mount Regulator (DMR) is a high-flow vacuum-referenced fuel pressure regulator that bolts directly to Radium fuel rails via its 8AN ORB union, eliminating extra plumbing. Finished in green.

The main inlet is 6AN ORB with an included union for 8AN ORB ports; either lower -6AN ORB port serves as the return, and two 1/8in NPT side ports accept a gauge or sensor. The 1:1 design flows over 1,400 lph with interchangeable orifices for pressure stability.
