Troubleshooting & FAQ

How do I know if this connector fits my Suzuki motor?

This connector is designed for a wide range of Suzuki 3.5HP to 140HP outboard motors (both 2-Stroke and 4-Stroke) that use a 5/16" (8mm) fuel hose. Please verify your engine's requirements and cross-reference the OEM part number GS31071.

What are the signs of a failing fuel connector?
