Yamaha - Float Chamber Body - Carburetor Fuel Reservoir - 6A1-14381-02-00

Overview

This is the part of the carb that holds fuel steady before it gets pulled into the engine, and when it’s working right, everything feels smooth and predictable. You don’t notice it when it’s doing its job—but once it’s worn, warped, or dirty, the engine starts acting up fast. Rough idle, hesitation, or inconsistent running usually trace back here. It’s a simple component, but it plays a big role in how clean your motor runs.

Key Features

• Stable Fuel Reservoir – Maintains proper fuel level inside the carburetor for consistent operation.
• Precision Internal Design – Supports accurate fuel metering for smooth throttle response.
• Durable Marine Construction – Built to withstand fuel exposure, vibration, and harsh conditions.
• OEM Fitment Accuracy – Matches Yamaha specifications for proper sealing and alignment.
