Dominator HP #30 Air Bleed

The Holley Dominator HP #30 Air Bleed is a precision carburetor metering component designed for tuners and performance builders who demand exact fuel atomization control. This air bleed restrictor is engineered to regulate the introduction of air into the fuel delivery circuit, a critical function in fine-tuning carburetor response across idle, transition, and cruise ranges.

At just 0.5 oz and engineered to Holley's exacting standards, the Dominator HP #30 Air Bleed functions by controlling emulsion—the precise mixing of air and fuel before it exits the metering jets. The #30 size specifies the orifice diameter, which directly governs how much air can bleed into the fuel stream. Larger numbers allow more air flow and leaner mixtures; smaller numbers restrict air and enrich the circuit.

Carburetor enthusiasts, engine builders, and dyno tuners rely on Holley air bleeds to dial in circuits on Dominator carburetors used in street, strip, and racing applications. Installation is straightforward—the air bleed screws into its port, typically located on the carburetor body. With tight tolerances and quality materials, Holley's Dominator line represents the gold standard in carburetor components.
