Yamaha – Float Chamber Gasket | Carburetor Sealing Component | 6A1-14384-00-00

Overview

When a carburetor starts leaking or running uneven, a lot of times it comes down to a worn gasket in the float bowl. This gasket seals the chamber where fuel sits before it’s pulled into the engine, so it has to stay tight and consistent. Once it dries out or gets brittle, you’ll start seeing leaks or fuel issues that are hard to ignore. It’s a small part, but it makes a big difference in keeping your carb working the way it should.

Key Features

• Fuel Bowl Sealing Surface – Creates a tight seal between the float chamber and carburetor body.
• Leak Prevention Design – Helps keep fuel contained and prevents messy or unsafe leaks.
• OEM Precision Fit – Matches Yamaha specifications for proper alignment and sealing.
• Fuel-Resistant Material – Built to withstand constant fuel exposure and heat cycles.

Engine & Boat Compatibility

Designed for Yamaha outboard engines equipped with carbureted fuel systems using this style of float chamber gasket. Commonly found in smaller to mid-range Yamaha engines where reliable fuel control is essential.
