It is designed for Johnson, Evinrude, and OMC systems, offering reliable performance in demanding marine environments. Best for boat owners with older Johnson/Evinrude or OMC fuel setups that require durable, corrosion-resistant connections.

Note that hose clamps are sold separately and must be purchased to secure the connection.
Attwood Mercury Tank Fitting, 3/8 Inch Hose
This chrome-plated brass fitting is compatible with Mercury and Mariner engines and tanks, providing a secure connection for portable fuel systems. It supports multiple fuel types, including leaded and unleaded, as well as ethanol- and alcohol-blended fuels. Best for Mercury/Mariner users needing a robust, corrosion-resistant connection. A limitation is that it targets Mercury/Mariner ecosystems, so verify engine compatibility before purchasing.
Attwood 8897-6 Brass Quick-Connect 1/4-Inch NPT
This solid brass quick-connect fitting features a 1/4-inch NPT male thread for easy installation. It’s versatile for use with certain Mercury/Mariner engines that handle leaded, unleaded, and alcohol-blended fuels. Best for Mercury/Mariner owners seeking straightforward, quick-connect options. Avoid this if your system requires a different threading standard not covered by NPT adapters.
Attwood Universal Sprayless Connector ¼-Inch NPT
This sprayless connector replaces traditional tank fittings to prevent fuel spray during connection or disconnection. It has a high-strength body designed to endure marine conditions, and a 1/4-inch NPT male thread fits standard fittings. Best for users prioritizing safety during fueling. A limitation is that it may not fit non-standard tank configurations without adapters.
QuickMarine Universal Sprayless Connector Kit
The universal sprayless kit includes male and female sprayless connectors designed to eliminate fuel spray during connection.

Buying Guide
Key considerations when selecting boat fuel fittings include material, compatibility, and intended use. Below are practical questions to help compare options.
- What engine brands are in my boat? Choose fittings listed as compatible with those engines to ensure proper connection.
- Is the fuel system portable or built-in? Portable systems often benefit from chrome-plated brass or sprayless connectors for safer fueling.
- Do I need a P/N or NPT thread vs. barb fittings? NPT is common for threaded tanks; barb fittings work well with hose clamps for certain setups.
- Will I be running ethanol-blended fuels? Some fittings advertise compatibility with multiple fuel types; verify if your fuel matches the stated options.
- Is hose flexibility important? Barb fittings require compatible ID hoses and clamps for a secure seal.
