RADIUM Engineering FPRD-RA Fuel Pressure Regulator Damper

The RADIUM Engineering Fuel Pressure Regulator Damper (FPRD-RA, Rotating Assembly) combines two key fuel system components in one high-flow unit. It is a fully functional performance fuel pressure regulator with a built-in fuel pulse damper. Combining them cuts down on separate parts and plumbing in performance and racing fuel systems.

Key Features:

• Integrated 1:1 fuel pulse damper helps stabilize the pressure pulses created by the fuel pump, injectors and regulator.
• High-flow design suits pumps flowing from about 100 to 1,400 liters per hour.
• Tool-less pressure adjustment on the A-series regulator. No jam nut or set screw is needed.
• Flexible mounting. It can be mounted in any direction, including upside down.
• Auxiliary gauge port for monitoring fuel pressure or temperature.
• E85 compatible and designed for universal applications.
• Vacuum/boost reference support for dynamic fuel pressure outside the damper's base static pressure range.

RADIUM Engineering builds precision fuel system components for motorsport and performance use. The RA-series regulators have been refined through track and bench testing to improve pressure management and stability. This regulator is not for use on the low-pressure side of mechanical fuel pumps.
