Fuel Pulse Damper Billet Alm 6an ORB 40-100PSI

The Fuel Pulse Damper Billet Aluminum 6AN ORB 40-100PSI from Holley is designed to smooth fuel pressure fluctuations in performance fuel systems, making it an essential component for serious fuel system upgrades. This product is particularly beneficial in turbocharged and supercharged applications, where fuel pump pulsation can create harmful pressure spikes. High-performance enthusiasts and professional mechanics will find this damper crucial for maintaining engine reliability.

Constructed from precision-machined billet aluminum, the damper features a 6AN ORB (O-ring boss) inlet and outlet, ensuring compatibility with standard -6 AN hoses or hard lines. The internal poppet valve design effectively absorbs pump pulsation across the 40–100 PSI operating range, protecting fuel injectors from pressure spikes while maintaining consistent feed pressure to the fuel rail. This compact damper measures 4.4 x 4.3 x 4.7 inches and weighs 0.5 lbs, allowing for flexible mounting in tight engine bays.

Ideal for EFI conversions and custom fuel system builds, this Holley damper is particularly suited for high-horsepower applications where stock fuel delivery systems may struggle with pressure harmonics. Its straightforward installation process involves positioning the damper between the fuel pump and fuel rail, ensuring a reliable and efficient fuel delivery system. With this product, users can bridge the gap between raw power and reliability in their performance vehicles.
