RADIUM Engineering 20-1528-00 Fuel Pressure Regulator Damper FPRD-RA - Black

The RADIUM Engineering FPRD-RA (Fuel Pressure Regulator Damper-Rotating Assembly) consolidates critical fuel system components into a high-flow package, combining a fully functional high performance pressure regulator with a unique built-in fuel pulse damper. This regulator is ideal for fuel pumps that flow from 100 to 1,400 liters per hour and features compatibility with all gasoline types including unleaded, leaded, oxygenated, and pre-mixes, as well as alcohol blends including methanol, ethanol, and E85.

Key Features:

• Large 10AN ORB (7/8"-14) threaded inlet (side) and outlet (bottom) ports with included -6AN and -8AN male adapter fittings
• Industry-first 360-degree swiveling vacuum reference port with double O-ring seal, allowing tool-free directional adjustment
• Tool-less pressure adjustment system - no jam nut or set screw required, with incremental detents for haptic feedback
• Two M6x1mm threaded mounting holes with included laser-cut anodized aluminum mounting plate and hardware, mountable in any direction including upside down
• 1/8" NPT auxiliary port for monitoring fuel pressure or temperature, includes preimpregnated PTFE plug
• Integrated 1:1 fuel pulse damper stabilizes fuel pressure with optimal damping efficiency at 40-105 psi (2.8-7.2 bar) static pressure
• Refined RA-series design with single stainless steel return orifice generating laminar flow for enhanced stability control

Complete kit includes main rotating assembly with damper, mounting bracket with M6x1mm hardware, barbed vacuum fittings (x2), vacuum plug fittings for returnless applications (x2), 1/4" push-to-connect fittings (x2), 3AN male vacuum fittings (x2), 6AN male adapters (x2), 8AN male adapters (x2), 1/8" NPT port plug, vacuum hose Y-adapter, and vacuum hose. Note: This regulator features a single inlet and single outlet (return) port and cannot be used in dead-head fuel systems - it must be plumbed after the fuel rail.
