Brass Float

The Holley Brass Float (SKU HLY116-4) is a precision carburetor component engineered for boaters and marine engine enthusiasts who demand reliability in demanding conditions. This side-hung, adjustable brass float serves as the fuel level regulator in Holley carburetors, maintaining consistent fuel delivery across varying throttle positions and sea states. Whether you're running a vintage marine engine or restoring a classic powerboat, this float is essential for smooth, predictable engine performance on the water.

Constructed from solid brass, this float combines corrosion resistance with weight precision—critical traits for marine environments where moisture and salt air accelerate degradation. The adjustable design allows you to fine-tune fuel bowl levels, optimizing carburetor response and preventing flooding or lean-running conditions that plague poorly tuned setups. The side-hung mounting configuration integrates seamlessly into Holley carburetor assemblies, and the compact 5 x 2.1 x 7-inch profile ensures it fits standard fuel bowl cavities without modification. At just 0.06 lbs, the float maintains buoyancy while delivering the durability expected from genuine Holley OEM components.

Marine mechanics and boat owners restoring or maintaining Holley-equipped engines will find this float indispensable for carburetor overhauls and tune-ups. If your engine is running rich (fouling plugs, smoking), surging at idle, or hesitating under load, a worn or compromised float is often the culprit. This genuine replacement restores proper fuel metering and engine response. Verify carburetor model compatibility before ordering, as Holley manufactures multiple float styles for different applications. Installation requires basic carburetor knowledge or professional service; the float mounts directly into the fuel bowl without additional hardware.
