Radium Fuel Pulse Damper OEM Style

Radium Fuel Pulse Damper — OEM Style, 3/8" NPT

The opening and closing of fuel injectors creates pressure pulses in the fuel rail that can lead to unstable fuel pressure. This OEM-quality fuel pulse damper absorbs those oscillations via an internal diaphragm, smoothing rail pressure throughout the RPM range. Particularly effective with high-flow injectors, it can also help resolve erratic surging idle caused by inconsistent fuel pressure.

This damper features a 3/8" NPT male thread with impregnated pipe thread paste pre-applied for a clean, leak-free installation.
