Radium Fuel Pressure Regulator-Damper

Fuel Pressure Regulator-Damper (FPD-R) by Radium Engineering

The Fuel Pressure Regulator-Damper (FPR-D) is the ultimate solution for consolidating critical fuel system components into a high-flow package. It is a fully functional high performance pressure regulator with a unique built-in fuel pulse damper, an industry first. The FPR-D is compatible with all gasoline and alcohol blends of fuel including E85.

Fuel Pressure Regulator: The 1:1 vacuum reference high flow design has been tested to regulate over 1,400 liters per hour. Two interchangeable orifices are included to match the amount of fuel bypassed for the application. This added precision will resist diaphragm flutter and optimize pressure stability. Furthermore, with the addition of interchangeable return orifices, the regulator is a good match for big to small powered engines. Fuel pressure is dialed in using the preload set screw on top. Unlike many others, the stainless steel adjustament screw has super fine threads for resisting vacuum/boost leaks and fine tuning fuel pressure.

Fuel Pulse Damper: The integrated 1:1 fuel pulse damper stabilizes fuel pressure created by the fuel pressure regulator, fuel pump, fuel injectors, etc. The base pressure requirement for maximum damping efficiency is 40-120psi (2.8-8.3bar). This range is base static pressure only. Any dynamic fuel pressure created by the rising rate FPR outside of this range is acceptable assuming the vacuum/boost reference line is connected.

The inlet (side) port and outlet (bottom) port feature large 10AN ORB (7/8"-14) threaded ports. Two -6AN and two -8AN adapter fittings are included to suit most aftermarket fuel systems. The 1/8" NPT auxilary port can be used for monitoring fuel pressure, temperature, etc. A plug is included if this port will not be used. The FPR-D assembly features two M6x1mm threaded mounting holes. A laser cut anodized aluminum mounting plate with countersink M6x1mm bolts/nuts are included. The FPR-D can be mounted any direction including upside down.
