Universal Range Fuel Rail Top Port Pulse Damper Kit (20-0176) by Radium®. Size: -8 AN ORB. 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. 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.
When you need a headlight bulb or a stop light switch, you may be tempted to just run down to the local auto parts chain store. But before you waste your time and gas only to find high prices and poor selection, check out our great assortment of bulbs and other electrical parts
Notes: FPD-R base pressure requirement = 40 - 45psi (static) The range above is base static fuel pressure only. Any dynamic fuel pressure created by a rising-rate FPR outside of this range is acceptable, but only when the base "static" fuel pressure is set within these ranges and the vacuum/boost reference line is hooked up
