Fuel Regulator/Damper Kit Billet Alm 40-70 PSI

The Fuel Regulator/Damper Kit Billet Aluminum 40-70 PSI from HOLLEY is engineered for serious engine builders and performance enthusiasts who demand precise fuel delivery across dynamic driving conditions. This regulator serves as the critical control point in any fuel system, maintaining consistent pressure while absorbing pump noise and pulsation that can degrade injector response and fuel quality. Whether you're running a carbureted engine, EFI conversion, or high-output naturally aspirated build, this billet aluminum unit handles the rigorous demands of street and strip applications.

Constructed from precision-machined billet aluminum, this fuel regulator/damper combo delivers the durability and thermal stability needed for sustained performance. The 40–70 PSI adjustment range accommodates everything from mild carbureted setups to aggressive fuel-injected systems, allowing you to dial in the exact pressure your fuel system and injectors require for optimal atomization and combustion. The integrated damper function smooths out fuel pump ripple and pressure spikes, protecting injector seals and ensuring clean idle quality, crisp throttle response, and maximum horsepower extraction across the RPM band.

This regulator is ideal for custom engine swaps, turbocharged and supercharged builds, and any project where factory fuel control falls short. Installation is straightforward in-line with your fuel rail or carb supply line; the compact 4.4 × 4.3 × 4.8 inch footprint and 1.3 lb weight make it easy to mount without compromising engine bay layout. HOLLEY's reputation for engineering reliability means you can trust this unit through countless dyno pulls, track days, and street miles with confidence in consistent, repeatable fuel delivery.
