Radium Engineering Fuel Pulse Damper - R 8AN ORB - Swivel

Radium Engineering Fuel Pulse Damper - R 8AN ORB - Swivel Fuel pulse damper for EFI fuel systems. Screws into a female 8AN ORB port (such as on a fuel rail). Damper body swivels after installation. Compatible with all fuels. BRAND NEW IN BOX 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 injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.
