Nitrophyl Float Wedge - Primary

The Nitrophyl Float Wedge - Primary from Quick Fuel Technology is a precision carburetor float engineered for circle track racing and high-performance street applications where fuel delivery consistency directly impacts engine power and reliability. This center-hung, wedge-shaped float assembly serves as the fuel level regulator in Holley and Quick Fuel carburetors, maintaining optimal fuel charge in the bowl regardless of engine load, vehicle attitude, or cornering g-forces. For serious racers and performance enthusiasts, float selection is as critical as jetting—the wrong float causes lean stumbles, flooding, or fuel starvation under acceleration.

Constructed from Nitrophyl, a synthetic rubber-based composite material, this wedge float offers superior durability and chemical resistance compared to traditional brass or cork floats, resisting degradation from modern fuel blends, ethanol, and nitro exposure. The wedge geometry is optimized for center-hung mounting, allowing unrestricted float bowl airflow while providing precise fulcrum positioning that minimizes needle valve wear. At just 0.06 lbs, the lightweight design reduces inertial lag during acceleration and deceleration events, enabling faster float response and tighter fuel level regulation—critical when running on the edge of lean-out at full throttle or navigating high-speed turns.

Circle track competitors, bracket racers, and street performance builders rely on the Nitrophyl Float Wedge - Primary to maintain consistent fuel levels across varying fuel pressure, temperature, and g-load conditions that traditional floats cannot handle. Direct replacement for OEM Holley and Quick Fuel carburetors simplifies installation—no modification or tuning required. Verify carburetor model and float bowl type before ordering to ensure correct primary float specification and optimal performance.
