Radium Engineering FPD Direct Mount Fuel Pulse Damper

$82.00$91.00

The Radium FPD (fuel pulse Damper) helps to ensure your high power high boost engine running BIG injectors idles and runs as close to stock as possible. The opening and closing of fuel injectors creates pressure pulses in the fuel rail which lead to oscillating fuel pressure. This oscillation in fuel pressure causes small differences in the amount of fuel injected during each injector pulse. In order to achieve a safe and consistent fuel pressure in the fuel rail a fuel pulse damper (FPD) is often necessary. The FPD’s internal diaphragm absorbs 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 injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced do to the fuel pressure oscillations.
