Radium FPD-R Fuel Pulse Dampener - 3/8" NPT Fuel Pulse Dampeners Dynamic fuel pressure created byRadium FPD R Fuel Pulse Damper 3 8" NPT The opening and closing of fuel injectors creates pressure pulses in the fuel rail that can lead to unstable fuel pressure. A fuel pulse damper (FPD) absorbs these oscillating pulses via an internal diaphragm to stabilise rail pressure throughout the RPM range. This can help resolve idle surge (especially with high flow injectors) and erratic lean AFR spikes commonly experienced as stumbling that are difficult
