The Quick Fuel Technology Viton Needle & Seat with .130 orifice is a precision fuel-metering component engineered for adjustable carburetor systems, specifically designed for Holley and Quick Fuel carburetors. This needle and seat assembly regulates fuel flow into the carburetor bowl, maintaining consistent fuel pressure and level critical for accurate engine tuning and reliable performance across varying load conditions.
The .130 orifice size controls the fuel delivery rate, making this component essential for carburetor jetting and calibration. Constructed with Viton seals, this needle and seat assembly resists fuel degradation and maintains reliable sealing over extended use, even with modern ethanol-blended fuels that can degrade standard rubber compounds. The adjustable design allows tuners to fine-tune fuel metering for specific engine combinations, air density, and fuel type requirements—critical for optimizing air-fuel ratios on street and competition vehicles alike.
This component is ideal for carburetor rebuilds, performance tuning adjustments, and replacement of worn or damaged needle and seat assemblies on Quick Fuel and Holley carburetor platforms. Whether performing routine maintenance or dialing in a freshly tuned engine, having a high-quality replacement needle and seat assembly on hand ensures continuity in fuel metering precision. The compact, lightweight design integrates seamlessly into existing carburetor installations without modification.
Carburetor tuners and engine builders recognize the importance of quality fuel-metering components in achieving repeatable, stable engine performance. The .130 orifice size is a common specification across many high-performance and street applications, making this needle and seat assembly a practical stock item for shop inventory and DIY enthusiast garages.
Sold as a single unit, this Quick Fuel Technology needle and seat assembly supports carburetor maintenance, restoration projects, and performance tuning workflows across the automotive aftermarket.
