Sierra 80012 Replacement VST O-Ring for Suzuki Outboards
A direct-fit replacement O-ring for the Vapor Separator Tank (VST) on Suzuki outboard engines. The VST O-ring provides the primary seal between the VST body and its cover — when it hardens, cracks, or takes a compression set, fuel vapors can escape and the VST may not hold pressure correctly, leading to hard-start or no-start conditions.
Sierra manufactures this O-ring to OEM specifications, ensuring correct dimensions and material compatibility with Suzuki fuel system components.
Key Specs
- Fits: Suzuki outboard engines (VST application)
- Function: Vapor Separator Tank (VST) body-to-cover seal
- Manufacturer: Sierra (OEM-equivalent)
- Part Number: 80012 / Sierra 47-80012
Parts Desk Insights
Best used as a preventive replacement during any VST service, fuel injector cleaning, or high-pressure fuel pump replacement on Suzuki outboards. The VST O-ring is a low-cost component that is easy to overlook — but if it’s not replaced when the VST is opened, a hardened or deformed O-ring can cause a fuel leak or pressure loss that sends you back to the shop. Always replace this O-ring any time the VST cover is removed, regardless of whether the old one looks serviceable. Confirm fitment against your engine’s service manual or parts diagram before ordering, as VST O-ring dimensions vary across Suzuki engine families and model years.
