The Dominator HP #40 Air Bleed is an essential tuning component for high-performance carbureted engines seeking precise fuel delivery and optimal air-fuel mixture control. This Holley air bleed jet is designed for enthusiasts and professional mechanics who demand reliability and repeatability in engine calibration. Whether you're building a street rod, drag racing platform, or restoring a classic muscle car, the Dominator HP #40 allows you to dial in your carburetor's fuel curve with surgical precision across the RPM band.
Air bleeds work by metering a controlled amount of atmospheric air into the fuel circuit, effectively leaning the mixture during cruise and light-load conditions while allowing richer operation under full throttle and acceleration. The #40 sizing in this Holley component provides a specific orifice diameter that matches intermediate performance applications and is widely used in modified small-block and big-block combinations. By adjusting air bleed selection, tuners can compensate for altitude, fuel type, and engine modifications without replacing primary jets, making this a cost-effective alternative to complete carburetor rejetification. The compact design (3.5 x 0.5 x 5 inches) and lightweight construction (0.04 lbs) ensure easy installation and no impact on carburetor balance or mounting.
Dominator HP #40 Air Bleed jets are compatible with all Holley four-barrel and two-barrel carburetors featuring standard air bleed boss configurations, including the legendary Dominator series and Street Avenger models. This product is ideal for engine builders transitioning from stock carburetion to performance fuel delivery, turbocharged applications requiring mixture control, and vintage race cars where emissions tuning isn't a concern. Professional installers and DIY builders alike trust Holley air bleeds for repeatable results and OEM-quality manufacturing standards. Simple installation requires only a small wrench or pliers, making this an accessible upgrade for any skill level.
