Radium Engineering FPD-XR Direct Mount 3/8 NPT Fuel Pulse Damper Kit vendor_APR of torque and had aPart #: 20 0179 The 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. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow
