Put A Stop To Fuel Pressure Pulsing In Your Fuel System With One Of Holley's Fuel Pulse Dampers

11/07/2023

Whether you need a damper depends on a few things. If your vehicle has quick changes in fuel pressure caused by injector pulses, especially with high-flowing injectors and low volume fuel rails, you might need a damper. These pressure changes, especially between 3 and 5 thousand RPM, can make the engine run unevenly and cause stumbling during acceleration. Cars with mostly hard metal tubing are more affected by these changes than ones with soft lines. Also, cars with systems that regulate fuel pressure near the gas tank might experience stronger changes in pressure because of the regulator's delay in responding.


Holley’s Fuel pulse dampers provide consistent fuel pressure for efficient combustion and optimal engine performance. Fuel pulse dampers work alongside the fuel pressure regulator to manage fuel pressure effectively. They smooth out the pressure pulsations caused by the rapid opening and closing of fuel injectors, as well as the operation of the fuel pump.
