Attwood 8889LP6 Acetal 3/8-Inch Barb Fuel Hose Female Tank Fitting
The 8889LP6 is designed for 3/8-inch I.D. fuel hoses, featuring an acetal body and a barbed connection for secure hose attachment. It is specifically intended for use with Johnson/Evinrude/OMC brand engines and tanks, ensuring compatibility with common marine setups. Best for boaters with Johnson/Evinrude/OMC systems who need a durable, low-permeation connection and plan to source clamps separately. A potential limitation is the requirement to purchase hose clamps separately, which adds a small extra step to installation.
Attwood Brass Quick-Connect Tank Fitting 1/4 Inch
This solid machined brass quick-connect offers robust durability and corrosion resistance in marine environments. The 1/4-inch NPT male thread enables fast, secure hookup with compatible fuel tanks. It is designed to work with Johnson, Evinrude, and OMC engines and tanks, making it a reliable choice for standard marine fuel systems. Best for installers seeking a simple, tool-free connection and the reassurance of brass construction. Limitation: brass components may require care against electrochemical corrosion in aggressive saltwater conditions; ensure proper gaskets and seals.
Attwood Low‑Permeation 3/8 Inch Barb Female, Acetal Quick‑Connect
Built with solid machined brass components and a quick-connect 1/4-inch male thread, this connector is designed for quick, tight installations. It works with 8896-6 hose fittings and is suitable for use with leaded, unleaded, and ethanol-blended fuels. Best for users who want a low-permeation option and dependable compatibility with Attwood fittings. A potential limitation is the need to verify hose compatibility with your specific tank and line sizes before purchase.
Attwood 88FHE516-6 Johnson/Evinrude/OMC Fuel Hose Fitting, 5/16-Inch
This 5/16-inch fuel hose fitting is molded in acetal and fits Attwood tank fittings such as 8883-6. It suits boats using 5/16-inch hoses and offers a solid, marine-grade connection. Best for Attwood system users who require a precise match to 8883-6 tanks. Limitation: not ideal for 3/8-inch hoses; choose this when your hose size matches the 5/16-inch spec.
iFJF 32-858104K08 Outboard Fuel Line Kit
The iFJF kit is sized for Yamaha and Mercury/Jonson/OMC outboards and includes a 10-foot fuel line with a primer bulb and a female connector. It’s designed for 5/16″ lines in many Yamaha models and provides a complete replacement solution for outboard fuel lines. Best for boaters needing a longer, ready-to-install kit with a primer bulb. Limitation: some newer high-horsepower models may not support external fuel tanks, so verify compatibility with your engine model before purchase.
Buying Guide: Key Purchase Considerations
First, confirm hose size compatibility. Most marine fittings are labeled for 3/8″ or 5/16″ I.D. lines. Choosing the correct barb size ensures a tight seal and reduces the risk of leaks. Look for quick-connect features if you want faster maintenance and easier disconnections in the field.
Material matters. Acetal and brass are common for marine fuel fittings. Brass provides strength and corrosion resistance, especially in saltwater environments, while acetal components offer good chemical compatibility and lighter weight. Consider low-permeation options if you’re concerned about fuel vapor exposure.
Engine compatibility. Ports and threads differ by brand (Johnson/Evinrude/OMC, Yamaha, Mercury). Verify that the product lists your engine brand and tank type to avoid misfits that require adapters. Some Attwood fittings are specifically marketed for certain engine families.
Installation notes. Some fittings require separate hose clamps or gaskets. Check if a kit includes all necessary components or whether extra parts are needed. Quick-connect models can simplify routine maintenance but may require periodic inspection to ensure a secure connection.
Durability and environment. Marine fittings endure vibration, sun exposure, and salt spray. Look for corrosion-resistant materials and durable seals. If you operate in corrosive environments, prioritize brass or reinforced components and inspect fittings regularly.
Frequently Asked Questions
- What is a boat gas line connector used for?
It connects fuel lines to tanks or engines, ensuring a secure, leak-free fuel pathway. - Which size is common for boat fuel lines?
Common sizes include 3/8 inch and 5/16 inch inner diameters. Measure your hose to confirm. - Are brass fittings better than acetal for saltwater use?
Brass offers higher corrosion resistance in saltwater, but both materials are commonly used and rated for marine fuel systems. - Do quick-connect fittings require tools?
