WARNING! Exercise extreme CAUTION when working with fuel systems. Do not smoke or expose the
working area to any spark or flame. Work in a well-ventilated area. Clean up all spilled fuel immediately
and dispose cleaning materials in a sealed metal trash container. Relieve fuel pressure prior to working on
the fuel system. To prevent failure, all O-ring fittings MUST be lubricated prior to assembly.
The DMR is a high flowing Radium Engineering fuel pressure regulator that mounts directly to a fuel rail. The fuel rail adapter
features a unique O-ring design that permits the entire unit to swivel when installed (Port A). For ideal hose routing, either of the
two opposing 6AN ORB (9/16"-18 threaded) female ports (B and C) can be used for the fuel return connection. The unused return
port should be plugged using the included fitting.
