The .110 Viton Needle & Seat 10-Pack (Part Number 5110X) is a precision carburetor fuel metering component designed for Holley and Quick Fuel carburetors. This adjustable needle and seat assembly controls fuel flow into the float bowl, directly influencing fuel pressure stability and engine idle quality. The 0.110 orifice size is engineered for specific fuel delivery requirements, making it essential for carburetor tuning, rebuild kits, and performance maintenance on both street and competition engines.
Viton sealing material provides superior chemical resistance compared to traditional rubber, resisting fuel degradation, ethanol blends, and temperature extremes encountered in high-performance applications. The 10-pack quantity allows for rebuilding multiple carburetors or maintaining spares for race day, dyno tuning sessions, or fleet maintenance operations. Precision machining ensures consistent fit and reliable sealing across multiple installation cycles, critical for maintaining proper fuel pressure regulation and preventing lean-out conditions during acceleration.
This component is essential for anyone performing carburetor restoration, engine rebuild work, or fuel system diagnostics on Holley and Quick Fuel equipped vehicles. Rebuilding or replacing worn needle and seat assemblies directly addresses fuel leakage, inconsistent idle, and poor drivability symptoms that emerge after extended engine operation. The adjustable design accommodates fine-tuning of fuel pressure and delivery characteristics during carburetor setup and tuning procedures.
Carburetor fuel metering components wear gradually through normal operation; periodic inspection and replacement ensure engine performance remains consistent. Whether you're a restoration enthusiast, performance tuner, or professional mechanic, maintaining spare needle and seat assemblies on hand prevents downtime and supports proper carburetor function. The Viton material standard and 0.110 orifice specification make this pack compatible with common Holley and Quick Fuel carburetor platforms used in street rods, muscle cars, marine engines, and classic automotive applications.
