Fuel Pulse Damper Inline 6an ORB 40-70PSI

The Fuel Pulse Damper Inline 6AN ORB 40-70PSI by Holley is a critical component for fuel-injected engines that utilize high-performance fuel systems or aftermarket fuel pumps. Fuel pulsation can lead to issues such as degraded fuel regulators and damaged injectors, which ultimately affect engine performance and reliability. This damper is designed to mitigate those pulsations, ensuring a stable fuel delivery system.

Engineered for a pressure range of 40 to 70 PSI, the Fuel Pulse Damper features a sealed internal diaphragm and spring mechanism that effectively absorbs shock waves generated by fuel pump operation. The 6AN ORB (O-Ring Boss) inlet and outlet ports facilitate easy integration into existing fuel lines using standard -6 hose fittings. Its aluminum housing is resistant to corrosion, making it suitable for various environments.

This damper is particularly beneficial for applications involving carbureted-to-fuel-injection conversions, turbocharged or supercharged engines, and builds utilizing external or high-volume fuel pumps. It should be installed between the fuel pump outlet and the fuel rail to effectively manage pulsation noise and pressure spikes, enhancing overall fuel system stability.
