Dominator HP #28 Air Bleed

The Dominator HP #28 Air Bleed from Holley is a precision carburetor tuning component designed for high-performance engine builders, fuel system technicians, and dedicated enthusiasts who demand exact air-fuel mixture control. This set of ten brass air bleeds represents the gold standard in carburetor calibration, addressing the critical need for repeatable, dialed-in jetting across demanding racing and street applications. Available for immediate sale, the Dominator HP #28 Air Bleed delivers the meticulous flow control that separates mediocre carburetor tune-ups from championship-level performance.

Each air bleed features a precisely engineered 0.028-inch internal diameter in solid brass construction, the material choice that ensures longevity and resistance to fuel degradation in high-ethanol and traditional fuel environments. The #28 size sits in the mid-range of Holley's air bleed catalog, making it ideal for street-strip combinations and moderate-displacement engines running standard fuel pressure. Brass construction resists corrosion and maintains dimensional stability across repeated tuning cycles, critical for carburetors that undergo frequent jetting adjustments during break-in, seasonal transitions, or altitude compensation. The ten-piece set format acknowledges that serious tuners maintain an inventory of common sizes for rapid on-track adjustments and baseline testing.

Technicians working with Holley Dominator HP carburetors and compatible Holley four-barrel platforms benefit most from stocking multiple #28 air bleeds, as this size addresses emulsion tube and main well tuning requirements across popular engine combinations. Installation requires carburetor removal and careful drilling-out or removal of existing bleeds—a task for experienced builders with proper tools and carburetor knowledge. The compact 0.65-inch width and 3.45-inch length accommodate standard Dominator HP tower spacing, ensuring drop-in compatibility without modification. Whether you're dialing in a fresh stroker, compensating for winter blend fuel, or building a repeatable test configuration, the Dominator HP #28 Air Bleed set provides the precision components required for professional-grade carburetor tuning.
