Engine bays with limited room for a regulator and its hose runs are exactly what the DMR-RA is sized for. It threads directly into a -8 ORB fuel rail port through a 360-degree swiveling adapter, eliminating the extra fitting and hose that a remote-mounted regulator would need, or it can be mounted off-rail using a separate base when direct mounting isn't practical. A tool-less adjustment knob with 1 psi detents and a single stainless steel return orifice keep pressure setting and stability consistent.

Radium Engineering 20162300 DMR-RA Direct Mount Fuel Pressure Regulator Features:

• Mounts directly to a compatible -8 ORB fuel rail port via the included 360-degree swiveling adapter.
• Main inlet port is female -6 ORB; bottom return port is also -6 ORB with a 360-degree swiveling -6 AN male fitting.
• Tool-less adjustment knob with incremental 1 psi (+/-0.5 psi) detents for haptic feedback while setting pressure.
• Two 1/8 in. NPT side ports accept a gauge, transducer, or temperature probe; PTFE plugs included if unused.
• Single stainless steel return orifice generates laminar flow for improved pressure stability.
• Minimum regulated pressure is 18.5 psi (1.3 bar); compact body clears tight engine bay spaces.
