Radium Fuel Pulse Damper Xr Inline 8An WRXLink From PCB revision 1The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary Which damper do I choose? The FPD R (Fuel Pulse Damper Range) and FPD XR (Fuel Pulse Damper Extra Range) both have unique base "static" fuel pressure requirements: FPD R base pressure requirement = 40 70psi (static) FPD XR base
