Viton Needle & Seat - .110

The Viton Needle & Seat - .110 from Quick Fuel Technology is a precision fuel delivery component engineered for carburetors that demand reliable, adjustable metering control. Designed for both Holley and Quick Fuel carburetors, this needle and seat assembly serves as the critical valve that regulates fuel flow into the float bowl, making it essential for any builder or mechanic seeking to fine-tune fuel delivery on street, strip, or competition applications. Whether you're diagnosing a lean condition, recovering from fuel starvation, or optimizing a fresh carburetor build, this direct-fit replacement component offers the adjustability needed to dial in precise fuel pressure and float levels.

Built from Viton elastomer sealing material, this needle and seat assembly resists fuel degradation and temperature cycling far better than standard rubber compounds, ensuring consistent sealing performance across extended engine operation and seasonal storage. The .110 orifice specification defines the flow capacity of the fuel passage, allowing experienced tuners to select the exact size required for their fuel pressure curve and engine demand. The adjustable design permits field modification without complete carburetor disassembly, reducing downtime and enabling real-time correction during dyno tuning or track testing. Viton's inherent resistance to gasoline and ethanol blends makes this assembly particularly valuable for modern fuel systems and extended-use scenarios where fuel chemistry or temperature fluctuations would compromise inferior sealing materials.

Carburetor enthusiasts, performance engine builders, and restoration specialists will find this needle and seat essential for correcting float bowl issues, resolving hesitation or flooding, or converting older carburetors to adjustable configurations. Installation fits directly into Quick Fuel and Holley carburetor bodies, requiring only basic hand tools and familiarity with carburetor assembly procedures. The compact, lightweight design (0.04 lbs) makes it practical to stock as a replacement part in your shop or mobile tuning kit, ensuring you're never stranded by a faulty float bowl seal during a critical rebuild or competition weekend.
