Radium RA-Series FPR Conversion Kit, Green

Application: Radium adjustable fuel pressure regulators – DMR, MPR and FPR damper (all generations), and Radium hangers / surge tanks with an integrated regulator
Part Type: FPR conversion kit, RA-Series
Part Number: 20-1101-01

This Radium Engineering kit converts previous Radium adjustable fuel pressure regulators to the RA-Series design, adding the newest features and performance improvements to older regulators.

RA-Series regulators offer tool-less pressure adjustment – no jam nut or set screw, just turn the knob – with detents that give haptic feedback and roughly 1psi (+/-0.5psi) per click. A redesigned single stainless steel return orifice generates laminar flow for better pressure stability, and the 360 degree swivelling, double O-ring sealed vacuum reference port can be pointed in any direction without tools.

Key Features

  • Tool-less Adjustment: Turn the knob; detents give about 1psi (+/-0.5psi) per click
  • Minimum Pressure: 1.3bar (18.5psi)
  • Maximum Pressure: Not limited by the regulator – set by the pump relief valve or pump controller current limit
  • Vacuum Reference: 1:1 rising rate, 360 degree swivel, double O-ring sealed, four interchangeable #10-32 fittings
  • Return Orifice: Single stainless steel orifice for laminar flow and stability
  • Fuel Compatibility: All petrol types (unleaded, leaded, oxygenated, premixed) and alcohol blends incl. methanol, ethanol and E85

What's Included

  • Upper rotating assembly
  • 5mm (3/16in) barbed vacuum fitting
  • Vacuum plug fitting (returnless)
  • 1/4in push-to-connect vacuum fitting
  • 3AN male vacuum fitting
  • Anodised half-moon retainers
  • Stainless steel return orifice
  • Stainless steel button head screws
  • Stainless steel spring
  • Fluorosilicone diaphragm

Important Notes

  • Use a wicking medium-strength threadlocker on the vacuum fitting
  • Radium's instructions: return orifice 4.0Nm (35 in-lb), top cap screws 0.7Nm (6 in-lb) in a cross pattern; do not reuse the old spring hat
  • A rapid fall in fuel pressure after the pump shuts off is normal for high-flow aftermarket regulators and is not a defect – pressure resets as soon as the pump runs
  • Long cranking or slow pressure build is unrelated to the regulator – check for feed line drain-back (e.g. a jet pump leak or missing pump check valve)
  • The vacuum plug is for returnless systems where the regulator cannot be vacuum referenced
  • Installation instructions are available in the Instructions tab

Vehicle Fitment

  • Radium Direct Mount Regulator (DMR) – all generations
  • Radium Multi-Port Regulator (MPR) – all generations
  • Radium Fuel Pressure Regulator Damper – all generations
  • Radium hangers and surge tanks with integrated regulator
