Sierra 18-80012 VST O-Ring for Suzuki Outboard Motors

The Sierra 18-80012 is a replacement VST (Vapor Separation Tank) O-Ring designed specifically for Suzuki outboard engines. This precision-engineered seal creates a critical fuel-tight barrier within the vapor separation system, preventing fuel leaks and maintaining proper fuel pressure delivery to the engine.

Key Features:

• Direct replacement for Suzuki OEM VST o-ring components
• Fuel-resistant elastomer construction for long-lasting durability
• Precision-molded dimensions ensure proper fit and seal integrity
• Prevents fuel vapor leaks and maintains system pressure
• Essential component for VST fuel pump maintenance and rebuild

This o-ring is a critical wear item that should be replaced during VST fuel pump service or any time the vapor separation tank is disassembled. Using a fresh o-ring ensures reliable sealing and prevents fuel system problems caused by deteriorated seals.
