Radium V2 FPD-R Fuel Pulse Dampener - 8AN ORB Standard Hex Socket Aluminum hats are CNC machinedV2 FPD: Even after tightened, the newest 8AN ORB dampers (20 0776 and 20 0777), will swivel permiting the vacuum port to be clocked 360 degrees. 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
