Radium Engineering MPR Multi-Port Regulator - Universal
The Radium Engineering Multi-Port Regulator (MPR) is a flexible fuel pressure regulator for both simple and complex EFI fuel systems. Its port layout lets it combine two pumps into a single feed, split a feed between two fuel rails, or run a single-pump setup, in flow-through, deadhead or hybrid configurations.
Like all RA-Series regulators it offers tool-less pressure adjustment: turn the knob and haptic detents give roughly 1 psi per click. A laminar-flow return orifice gives stable pressure, integrated dual return ports line up with the pressure ports so no elbows are needed, and the double O-ring sealed vacuum reference port swivels 360 degrees and accepts four interchangeable fittings. Choose black (20-1100-00) or green (20-1100-01).
Note: Minimum fuel pressure is 18.5 psi (1.3 bar); maximum pressure depends on your fuel pump system. A rapid drop in fuel pressure after shut-off is normal for high-flow aftermarket regulators and resets as soon as the pump runs. Installation by a professional is recommended.
