6-32 Screw-in Restrictor Blanks (10-Pack)

The Quick Fuel Technology 6-32 Screw-in Restrictor Blanks (10-Pack) represent precision brass components engineered for carburetor tuning and emulsion jet configuration. These solid brass blanks feature the industry-standard 6-32 thread specification, allowing builders and restorationists to customize fuel delivery characteristics on Quick Fuel carburetors and compatible aftermarket carburetor platforms. The 10-pack format accommodates multiple carburetor configurations or provides inventory for ongoing engine development work.

As solid restrictor blanks, these components seal off specific emulsion tube pathways without reducing fuel flow through alternative circuits. The brass material resists corrosion and maintains dimensional stability across thermal cycling, critical in high-heat engine compartment environments. The 6-32 thread pitch is the standard for Quick Fuel's restrictor jet family, ensuring reliable fitment in factory and performance carburetor bodies. Blank configuration means these restrict fuel to the emulsion system entirely, making them essential for tuners who need to isolate fuel delivery routes during carburetor optimization or engine bay modifications.

These restrictor blanks serve hot rod enthusiasts, engine builders, carburetor restoration specialists, and performance tuners who calibrate fuel mixtures on vintage and modern muscle car platforms. Whether adjusting jetting for altitude changes, matching fuel delivery to an upgraded intake manifold, or rebuilding a carburetor to original specifications, having solid restrictor blanks on hand eliminates ordering delays. The Quick Fuel brand's reputation in circle-track racing and street performance carburetor development makes this 10-pack a trusted consumable for serious fuel system work.
