Quick Fuel Technology 7-7QFT Screw-In Restriction Blank Jets - 6-32

The Quick Fuel Technology 7-7QFT is a 6-32 threaded screw-in restriction blank designed for carburetor emulsion calibration and tuning. This precision-machined brass component allows racers and engine builders to block off unused restriction ports or serve as a starting point for custom drilling to specific sizes.

Key Features:

• 6-32 thread size for universal fitment in Quick Fuel and Holley carburetors
• Solid blank design—no pre-drilled orifice for maximum tuning flexibility
• Durable brass construction for corrosion resistance and longevity
• Sold in pairs for convenient replacement or tuning applications
• Compatible with Quick Fuel Technology and Holley carburetors with center-hung floats

These restriction blanks are essential components for fine-tuning air/fuel ratios and emulsion characteristics in performance carburetors. The blank configuration allows experienced tuners to drill custom restriction sizes based on specific engine requirements, or simply plug unused passages during carburetor modifications.
