The Fuel Pulse Damper Inline 6AN ORB 40-100PSI by Holley is a precision fuel system component designed for high-performance engine builds. It is ideal for serious automotive enthusiasts and professional mechanics who work with forced induction, nitrous oxide systems, or aggressive carburetor tuning. This damper is essential for maintaining stable fuel pressure, which is critical for reliability and consistent power delivery.
Engineered to absorb harmful pressure spikes, the Fuel Pulse Damper utilizes a sealed hydro-pneumatic design that mitigates pressure oscillations and fuel hammer. The 6AN ORB (O-ring boss) inlet and outlet ports ensure a secure, leak-free connection for -6 braided hose or hardline fuel systems. With an operating range of 40–100 PSI, it is compatible with both mechanical fuel pumps and modern electric systems.
This compact damper, measuring 4.3 x 4.3 x 4.7 inches and weighing approximately 1 lb, allows for flexible mounting in engine bays with limited space. It is commonly installed between the fuel pump and carburetor, EFI fuel rail, or regulator inlet to enhance component longevity and tune stability. Upgrading to higher-flow fuel pumps or twin-fuel-pump setups is made easier with this essential component.
