Yamaha - Float Chamber Gasket Carburetor Fuel System 6E5-14384-02-00. Overview. Anytime you're opening up a carburetor, this is one of those parts you don't want to reuse. The float chamber gasket keeps fuel sealed where it belongs, and once it's been compressed and exposed to fuel, it doesn't seal the same twice. I've seen small leaks turn into messy carbs and rough-running engines just from skipping a new gasket. Replacing it keeps things clean, sealed, and running the way they should.. Key Features. Fuel-Tight Sealing Surface - Prevents leaks between the float chamber and carburetor body.. Fuel-Resistant Material - Built to handle constant exposure to gasoline without breaking down.. Maintains Proper Fuel Levels - Supports consistent carburetor operation by sealing the chamber correctly.. Exact OEM Fitment - Matches original specifications for proper alignment and easy installation.. Engine & Boat Compatibility. Designed for Yamaha 2-stroke outboard engines with carbureted fuel syst
