Nitrophyl Float - Road Race Notched

The Nitrophyl Float - Road Race Notched is a precision carburetor component engineered for high-performance marine engines that demand reliable fuel delivery under demanding conditions. Designed for boaters and engine builders who run Holley or Quick Fuel carburetors at their limits, this float assembly replaces worn or damaged factory units that compromise throttle response and fuel atomization. Whether you're tuning a race-ready inboard or restoring a vintage outboard to original specifications, a quality float is the often-overlooked foundation of consistent carburetor performance on the water.

Constructed from durable Nitrophyl material, this center-hung float features a double-wedge notched geometry that optimizes fuel level stability and minimizes sloshing during acceleration, deceleration, and rough water operation. The notched design enhances the float's ability to maintain precise fuel bowl height, ensuring the needle valve opens and closes at exact intervals—critical for keeping air-fuel ratios consistent whether you're idling through a no-wake zone or running full throttle. The compact 4.6 x 1.1 x 6.75-inch profile and lightweight 0.06 lb construction integrate seamlessly into the carburetor's fuel bowl without adding inertial mass that could delay needle response.

This Nitrophyl Float fits Holley and Quick Fuel carburetors equipped with center-hung float chambers, making it essential maintenance for anglers and boaters who rely on precise fuel metering during long days on the water. Installation is straightforward for anyone with basic carburetor familiarity—drop the notched float into its hanger pin and reassemble the fuel bowl. For best results, pair this replacement with fresh gaskets and verify float drop specifications according to your carburetor manufacturer's guidelines to maximize fuel economy and throttle control.
