Radium Engineering FPR-D Fuel Pressure Regulator/Damper, Green - 20-1528-01

Radium Engineering 20-1528-01 FPR-D fuel pressure regulator and pulse damper with a green anodized adjustment knob. Universal fit for EFI fuel systems.

• Combines an adjustable high-performance EFI fuel pressure regulator with a built-in fuel pulse damper
• The damper smooths pulsing from the injectors, the fuel pump and the regulator
• Single stainless steel return orifice for laminar flow and stability
• Single inlet and single return port. Not for dead-head systems; plumb it after the fuel rail
• Not for use with mechanical fuel pumps or direct injection, because pressure pulses can rupture the damper diaphragm
• Minimum pressure 18.5 psi (1.3 bar). Maximum 100+ psi, depending on the pump relief valve or fuel pump controller maximum current
• Damper base pressure range 40-105 psi (2.8-7.2 bar), static only. Outside this range the vacuum/boost reference is required for the damper
• Inlet (side) and outlet (bottom): 10AN ORB (7/8"-14)
• Auxiliary 1/8" NPT port for a fuel pressure gauge
• Two M6x1mm threaded body holes plus an anodized aluminum mounting plate. Can be mounted in any orientation, including upside down
• 360 degree swiveling vacuum reference, double O-ring sealed
• Compatible with unleaded, leaded, oxygenated and premix gasoline, and with methanol, ethanol and E85
