Dominator HP #43 Air Bleed

The Dominator HP #43 Air Bleed by HOLLEY is a precision carburetor air bleeding component designed for high-performance fuel delivery systems used in modified engines and competition vehicles. This small but critical component addresses a specific hydraulic function within carburetor circuits where precise fuel atomization and metering demand exact air introduction. Whether you're fine-tuning a street machine, drag racing platform, or restoring a classic muscle car, the correct air bleed size directly impacts cold start enrichment, throttle response, and overall fuel curve accuracy.

Air bleeds work by allowing controlled air into fuel circuits, which reduces fuel density in those passages and precisely regulates flow rates through metering jets and orifices. The #43 designation indicates this is a specific orifice size engineered to match Holley's Dominator HP carburetor architecture and the fuel enrichment demands of high-output naturally-aspirated or supercharged engines. At just 0.04 lbs and compact dimensions (3.5 x 0.55 x 4.95 inches), this component fits seamlessly into tight engine bay spaces while delivering repeatable, measurable performance improvements through proper jetting calibration.

Carburetor tuners, engine builders, and high-performance technicians rely on correctly sized air bleeds to eliminate lean spots during acceleration, prevent fuel starvation at peak RPM, and achieve repeatable dyno results. This component is essential for anyone rebuilding or upgrading a Dominator HP carburetor or matching fuel delivery to modified displacement, cam profiles, or increased boost levels. Installation requires carburetor disassembly and careful attention to circuit location; consulting your carb's schematic or a qualified fuel systems specialist ensures proper placement and optimal engine performance.
