Tame fuel-line pressure pulsations and keep injector delivery steady with the Standard Ignition Fuel Injection Pressure Damper (MPN FPD37). It installs as a front-position, direct-fit replacement for a range of Infiniti, Nissan, and Toyota engines listed below.
A fuel injection pressure damper is a mechanical device that absorbs the pressure spikes created as the injectors rapidly open and close, smoothing fluctuations in the fuel supply. This helps maintain a stable fuel pressure and can quiet the fuel-system noise those pulsations produce.
Signs the original damper may need replacing include audible fuel-line ticking or pulsation noise and inconsistent fuel pressure. If a failed damper is the cause, replacing it with FPD37 restores that function; diagnose the cause before replacing.
