Dominator HP #31 Air Bleed

The Dominator HP #31 Air Bleed is a precision-engineered brass component designed for carburetor tuning and fuel system optimization on high-performance engines. This air bleed jet serves a critical role in carb calibration, allowing experienced mechanics and engine builders to fine-tune the air-fuel mixture during cruise and part-throttle conditions. Whether you're dialing in a street machine, race engine, or classic hot rod, air bleed jets like the #31 are essential for achieving the optimal balance between performance, fuel economy, and drivability across different load ranges.

Manufactured by Holley, a leader in fuel system and carburetor technology, the Dominator HP #31 air bleed is machined from high-quality brass to ensure durability and precise orifice tolerances. The air bleed jet controls how much air bypasses the main fuel circuit, directly influencing fuel distribution and atomization in the idle and transition circuits. This specific #31 sizing is part of Holley's standardized bleed lineup, allowing tuners to systematically adjust mixture strength without replacing the entire carburetor or fuel delivery system. Its compact design (3.45 x 0.5 x 5 inches) and lightweight profile (0.03 lbs) make it easy to install and swap during dyno sessions or track adjustments.

Professional engine builders, drag racers, and street performance enthusiasts rely on Dominator HP air bleeds to achieve repeatable, data-driven carburetor tuning. If your Holley Dominator carb is running lean at cruise, surging off idle, or showing flat spots in the mid-range, swapping to the correct air bleed size is often the quickest fix before more invasive carb work is needed. Keep several sizes on hand during your next dyno session—air bleed jetting is one of the most effective and cost-efficient tools in the tuner's arsenal for fine-tuning response and fuel curve across the entire powerband.
