Yamaha - Float Chamber Body - Carburetor Component - 62Y-14381-40-00

Overview

On carbureted Yamahas, the float chamber is where everything starts to balance out. If the body gets worn or compromised, you’ll usually see it in how the engine runs—either too rich, too lean, or just inconsistent. I’ve replaced these on older setups where fuel control was all over the place, and it brought the motor right back to steady operation. Keep the fuel level controlled here, and the rest of the carb system has a much easier job.

Key Features

• Maintains Fuel Level Stability – Supports consistent fuel regulation inside the carburetor.
• Genuine Yamaha Fitment – Designed to match factory specs for proper sealing and alignment.
• Prevents Fuel Leaks – Helps contain fuel within the chamber to avoid overflow issues.
• Durable Marine Construction – Built to withstand fuel exposure and long-term use.
• Direct Replacement Component – Installs cleanly into existing carburetor assemblies.
