The Radium Engineering Multi-Port Regulator (MPR) is a high-flow vacuum-referenced fuel pressure regulator with an exceptionally flexible port layout, finished in green. Tested to regulate over 1,400 lph, it supports multi-pump and high-output fuel systems.
Ports A & B are -6AN ORB and port E is -8AN ORB for high-pressure fuel to/from the rail or pump, while the two lower opposing -6AN ORB return ports flow parallel for a clean return path. A 1:1 vacuum-reference design with interchangeable orifices resists diaphragm flutter for stable pressure.
