Radium Engineering FPD-R Fuel Rail Inline Pulse Damper 40-70psi 8AN ORB Green Top Legacy 6th Gen 313 in (33 mm) OutsideThe 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 Radium Engineering fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and often help idle surge, especially with high flow
