Dominator HP #34 Air Bleed

The Dominator HP #34 Air Bleed is a precision fuel metering component engineered for Holley carburetor platforms, delivering exact air-fuel mixture control in high-performance and street applications. As a seasoned mechanic, you know that carburetor tuning demands precision—and these brass air bleeds are the foundation of repeatable jetting adjustments. This set of 10 units gives you the flexibility to dial in multiple carburetors or maintain a spare inventory for quick troubleshooting and optimization on the dyno or at the track.

Manufactured from corrosion-resistant brass with a precisely machined 0.034-inch inner diameter, the Dominator HP #34 Air Bleed functions by controlling the emulsion of air into fuel circuits within the carburetor bowl and main discharge tubes. The #34 size sits in the mid-range of Holley's bleed catalog, making it ideal for moderate-displacement engines running pump fuel or mild nitrous applications. By restricting air entry at a calibrated rate, air bleeds reduce fuel flow bias at idle and cruise, promoting leaner mixtures where you need them while maintaining atomization under load—a critical balance that separates sloppy tuning from repeatable performance.

Carburetor builders, street rodders, and engine tuners rely on quality air bleeds to fine-tune response across the RPM band without relying solely on jet changes. The #34 works across Holley's classic 4-barrel lineup—including Dominator, Street Avenger, and Pro Series units—as well as select single-barrel and 2-barrel models. Keep a set on the shelf for testing different bleed combinations during baseline tuning; the compact design and durable brass construction ensure years of reliable service, and at just 0.04 lbs per piece, they're easy to swap during carburetor assembly or in-situ adjustments.
