Quick Fuel Technology Screw-In Air Bleed Restriction Jets

Quick Fuel Technology screw-in air bleed restriction jets are carburetor tuning components. They let you fine-tune air bleed and restriction calibration on compatible Quick Fuel and Holley HP-style carburetors. Air bleeds (also called air jets or air bleeders) control how much air mixes into each circuit of the metering block. Changing their size lets you adjust fuel mixture from idle through wide-open throttle.

Key Features:

• Screw-in design: Swap them externally with a simple hand tool, with no need to disassemble the carburetor.
• Tunable calibration: A larger air bleed opening leans out a circuit, and a smaller restriction richens it. This makes it easier to dial in idle, transition and cruise fueling.
• Precision-sized orifices: Available in a range of sizes to match your tuning needs.
• Blank versions: Blank restrictions can be drilled to a custom size for exact calibration.
• Quick Fuel Technology quality: Made by a brand known for race-proven carburetors and tuning parts.

Air bleed adjustments are often overlooked, but they are an effective way to refine carburetor performance for street, strip and racing builds. Use these jets as replacement parts or as tuning upgrades.
