Radium Engineering FPD-R Direct Mount 8AN ORB Fuel Pulse Damper Kit

The opening and closing of fuel injectors create pressure pulses that can lead to unstable fuel pressure, which this damper helps to correct. Its internal diaphragm absorbs oscillating pulses to maintain a consistent rail pressure, potentially resolving issues like idle surge and erratic lean air/fuel ratio spikes.

This damper features an anodized aluminum housing with selectable threaded male fittings, available in 8AN ORB or 3/8 NPT. It includes a vacuum/boost reference port for optimal performance, especially in boosted systems with a 1:1 rising rate fuel pressure regulator. The kit comes with the damper, a hose, necessary fittings/hardware, and instructions.
