Radium Engineering Fuel Pulse Damper-Xr, Inline, Barb

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. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. FPD-XR base pressure requirement = 40 - 120psi (static)Base pressure is the fuel pressure measured when the fuel pump is running WITHOUT a vacuum line connected to the regulator. Included -Anodized and laser engraved aluminum top, R=range or XR=extra range-Anodized aluminum body with male threads, 8AN ORB or 3/8 NPT-Stainless steel hardware-Rubber vacuum hose, 4mm ID-Vacuum hose Y-fitting This product is safe Compatible with use with all fuel types including alcohol blends such as E85. A fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as stumbling, that are difficult to tune out.� FPD-XR base pressure requirement = 40 - 120psi (static)
