Dominator HP #51 Air Bleed

The Dominator HP #51 Air Bleed from Holley is a precision carburetor tuning component engineered for fine-fuel metering control in high-performance and street engines. This set of 10 brass air bleeds is essential for anyone rebuilding, restoring, or optimizing a Holley carburetor—whether for classic muscle cars, hot rods, or performance builds. Air bleeds regulate the amount of air mixed into fuel circuits, directly affecting fuel atomization, idle quality, and throttle response across the engine's operating range.

Manufactured from brass for superior corrosion resistance and longevity, the Dominator HP #51 features a 0.051-inch inside diameter (ID) specification that controls precise fuel flow through the carburetor's air bleed circuit. Brass construction resists fuel and air degradation, ensuring consistent orifice size and accurate jetting over extended periods. The #51 designation corresponds to a specific orifice size within Holley's standardized bleed numbering system, allowing tuners to swap air bleeds methodically during carburetor calibration without guesswork. This set of 10 provides spare bleeds for multiple carburetors or facilitates A/B testing during the tuning process.

Carburetor experts, engine builders, and restoration specialists depend on Holley air bleeds to dial in fuel mixture, idle stability, and mid-range performance. Installation requires carburetor removal and partial disassembly; replacement is straightforward for technicians familiar with Holley four-barrel and two-barrel designs. The Dominator HP #51 Air Bleed is compatible with most Holley carburetor models that accept #51 bleeds, including Dominator, Street Avenger, and Spreadbore variants. Keep this set on hand for tuning adjustments, carburetor rebuilds, or performance diagnostics on any Holley-equipped application.
