FPR-D, Fuel Pressure Regulator-Damper
INSTALLATION INSTRUCTIONS can be downloaded here
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.
In the Box:
- Fuel pressure regulator-damper
- Aluminum mounting bracket
- Aluminum 6AN male adapter (x2)
- Aluminum 8AN male adapter (x2)
- Aluminum 1/8" NPT port plug
- Interchangeable return orifices
- M6x1mm mounting hardware
- Boost referenced Y-adapter
- Vacuum Hose, 3/32" ID
The graph below shows the minimum fuel pressure the regulator can achieve as a function of pump flow rate. This test was performed with the adjustment screw completely backed out, no preload.
For example, if you have two pumps that flow 320LPH (total 640LPH), the approximate minimum pressure the regulator can achieve is about 23.5 psi. Note: if an OEM fuel pressure regulator is used for 640LPH, it will likely not be able to bypass enough fuel.
With the Radium FPR-D, simply spin the set screw clockwise to achieve higher pressures. Note: Most EFI systems operate at 43.5 psi (3Bar) static fuel pressure.
