MSW’s Take: We’ve been using this damper on our Radium fuel rail equipped S54s for years now.
The opening and closing of the injectors creates pulses in the fuel rail, which can lead to unstable fuel pressure. This damper should be used (especially with high flow injectors) in order to achieve a safe and consistent rail pressure. The internal diaphragm will absorb oscillations and smooth fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle.
This OEM quality damper features a 3/8″ NPT male thread with impregnated pipe thread paste.
NOT TO BE USED ON THE LOW PRESSURE SIDE OF MECHANICAL FUEL PUMPS (INCLUDING DIRECT INJECTION.)
