Yamaha - VST Float Chamber Gasket - 6BG-14984-00-00

Overview

The Yamaha 6BG-14984-00-00 VST Float Chamber Gasket is a genuine OEM sealing gasket designed for the Vapor Separator Tank (VST) used in Yamaha EFI outboard engines. The VST system plays a critical role in regulating fuel delivery to the engine by maintaining a steady supply of fuel for the fuel injection system.

This gasket forms a tight seal between the VST float chamber and the housing, preventing fuel leaks and maintaining proper fuel pressure within the system. Over time, gaskets can become brittle or compressed due to fuel exposure, heat, and engine vibration. Replacing the VST float chamber gasket during fuel system service helps maintain proper sealing and reliable engine performance.
