FUEL PULSE DAMPER
Do I need a pulse damper? The opening and closing of the 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, pulse damper(s) should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle. 

If equipped, the OEM fuel pulse damper (shown above) can be reused with the Radium 14-0278 adapter fitting.
