Fuel Line Assemblies
Complete Fuel Line Assemblies for Marine Engines
Fuel line assemblies are critical components that safely transport fuel from the tank to your outboard engine, ensuring reliable performance on the water. These assemblies typically include fuel hose, primer bulbs, fuel line fittings, and stainless steel clamps—everything needed for a complete fuel delivery system. Modern marine fuel line assemblies are engineered to meet strict EPA, CARB, USCG, and ABYC requirements, featuring low-permeation materials that prevent fuel evaporation and reduce harmful emissions while maintaining compatibility with today's ethanol-blended fuels.
Whether you're replacing worn fuel lines or upgrading to meet current environmental standards, selecting the right fuel line assembly is essential for engine longevity and safety. Quality assemblies feature kink-resistant hose construction, fast-priming bulbs that maintain flexibility in extreme temperatures, and OEM-compatible fittings designed for specific engine manufacturers. The primer bulb is particularly important—it creates the initial fuel draw needed to start your engine and should be engineered to resist collapse in both hot and cold conditions.

Key Considerations When Shopping
When selecting a fuel line assembly, verify compatibility with your specific outboard engine manufacturer and model—fittings vary between Mercury, Yamaha, Johnson/Evinrude, and other brands. Pay attention to the internal diameter of the fuel line (typically 5/16" or 3/8"), as larger diameters provide maximum fuel flow for higher horsepower engines. Ensure your assembly includes low-permeation hose to comply with current environmental regulations, particularly if your vessel was manufactured after 2009. Regular inspection and timely replacement of fuel line assemblies prevents dangerous leaks, maintains optimal engine performance, and can save fuel costs by eliminating evaporative losses.
