Fuel pulse dampers, or pulsation dampers, act in tandem with the fuel pressure regulator to ensure stable and consistent fuel delivery to the engine. They do this by smoothing out the pressure fluctuations, or pulsations, caused by the injectors opening and closing, as well as the fuel pump operating.

AEM Electronics fuel pulse dampers feature billet aluminum construction with an anodized finish and are ideal for applications with large fuel injectors and high-volume fuel pumps. They are compatible with any fuel and available as a direct-mount or in-line style with a standard or extended psi range. Select the best fit for your fuel system.
