Radium Engineering DFPR Dual Fuel Pressure Regulator Universal

Radium Engineering DFPR Dual Fuel Pressure Regulator - Universal

The Radium Engineering DFPR (SKU 20-1102) is a dual fuel pressure regulator that isolates and controls two fuel circuits from a single inlet. It is ideal for modern engines running both direct and port injection, and for venturi transfer systems that are otherwise incompatible with fuel surge tanks. It also suppresses the pressure spikes created by mechanical high-pressure fuel pumps.

FPR1 feeds the direct injection high-pressure pump and FPR2 feeds the port injection rail(s), each with its own 1/8in NPT sensor port. Pressure is set with Radium's tool-less RA-series knob, with detents giving about 1 psi per click, while a stainless return orifice promotes laminar flow for stable pressure. The 360-degree swivelling vacuum port provides 1:1 rising rate reference.

Note: FPR2 pressure will always be equal to or lower than FPR1 – if rising rate pushes FPR2 above FPR1's setting, FPR1 will rise to match. FPR2 can be plugged if unused. A rapid pressure drop after shut-off is normal for high-flow regulators. Installation by a professional is recommended.
