Replacement Phenolic Floats

The Replacement Phenolic Floats for Quadrajet M4M carburetors are engineered as direct OEM replacements for operators and enthusiasts who demand reliable fuel delivery in high-performance engine applications. These floats maintain precise fuel level control within the carburetor bowl, a critical function for consistent engine performance, smooth idle quality, and predictable throttle response. Whether you're rebuilding a carb after extended service or replacing worn floats that have absorbed fuel over time, quality replacement floats are non-negotiable for maintaining factory-specification carburetor function.

Constructed from phenolic material, these floats deliver superior durability compared to traditional cork or foam alternatives. Phenolic compounds resist fuel absorption, which prevents the float from becoming waterlogged or losing buoyancy over extended storage or high-humidity conditions—a common failure mode in older carburetor systems. The side-hung design accommodates the specific geometry of Quadrajet M4M carburetors, ensuring exact fitment and proper pivot action. At just 0.06 lbs and measuring 2.7 x 1.85 x 5.05 inches, the compact profile integrates seamlessly into the carburetor bowl without modification.

This replacement phenolic float is ideal for carburetor rebuild kits, fleet maintenance programs, and vintage engine restoration projects where Quadrajet M4M carburetors are in service. Installation requires no specialized tools—simply remove the old float pin and swap in the new assembly. Technicians and engine builders rely on Edelbrock OEM-equivalent parts for consistency and long-term reliability, making this a trusted choice for both professional shop environments and serious enthusiasts maintaining classic and high-performance powerplants.
