Dominator HP #23 Air Bleed

The Holley Dominator HP #23 Air Bleed is a precision carburetor metering component designed for fine-tuning fuel delivery in high-performance gasoline engines. This brass air bleed jet (#23 size, 0.023-inch inner diameter) regulates the amount of air introduced into fuel circuits, directly controlling air-fuel mixture ratio and engine response across varying load conditions. The set of 10 provides multiple replacement and tuning options for carburetor setup and optimization.

Air bleeds are critical tuning elements in Holley carburetors, affecting idle quality, transition off-idle, and mid-range fuel economy. The #23 size represents a specific orifice diameter within Holley's standardized bleed sizing system; smaller numbers restrict air flow for richer mixture, while larger numbers allow more air for leaner mixtures. Brass construction resists corrosion and provides reliable performance in both fresh and long-term storage conditions. Technicians and engine builders select specific bleed sizes to compensate for altitude, fuel type, and engine modifications.

These bleeds are essential for carburetor rebuilds, performance tuning, and diagnostic troubleshooting on Holley four-barrel and two-barrel carburetors used in street, racing, and restoration applications. Users restoring vintage muscle cars, street rods, or optimizing carbureted performance engines rely on having multiple jet sizes on hand to dial in the precise air-fuel curve without delays. The compact size and minimal weight make this set practical to stock for workshop inventory.

Holley carburetors dominate the aftermarket performance and restoration market; original equipment and upgrade applications benefit from OEM-specification replacement jets and bleeds to maintain tunability and reliability.
