Product Details
This aftermarket female fuel line connector is intended for the fuel-tank end of compatible Mercury and Mariner outboard fuel line assemblies. It provides a quick-disconnect connection for applications using a 5/16 in (8 mm) fuel hose and a compatible male tank fitting.
Because connector designs can vary by engine, fuel tank, hose size, and serial-number range, compare the original connector and the applicable part references before ordering. The connector should be used only where the original assembly has the same tank-end connection style and hose size.
- Installation position: Female quick-disconnect connector at the fuel-tank end
- Hose size: 5/16 in (8 mm); verify against the existing hose before purchase
- Connection style: Clip-on quick disconnect
- Application: Compatible Mercury and Mariner fuel line assemblies
- Mating connection: Compatible male tank fitting; some listings reference 18-80402, but verify the fitting on your tank

Compatibility Information
This connector is intended for compatible Mercury and Mariner applications that use the corresponding female tank-end quick-disconnect and a 5/16 in (8 mm) fuel hose. Do not assume compatibility solely from engine horsepower, model family, or brand. Confirm the original connector, hose diameter, tank fitting, and any applicable model or serial-number requirements.
| Brand | Application | Connector Position | Hose Size | Verification Required |
|---|---|---|---|---|
| Mercury | Compatible outboard fuel line assemblies | Female tank end | 5/16 in (8 mm) | Compare original connector and tank fitting |
| Mariner | Compatible outboard fuel line assemblies | Female tank end | 5/16 in (8 mm) | Compare original connector and tank fitting |
Important: The reference information available for this listing does not establish one universal fitment range for every Mercury or Mariner engine year, horsepower rating, stroke type, or serial-number range. Check the exact application before installation.

Installation Notes
- Turn off the engine, remove ignition sources, and work in a well-ventilated area.
- Allow the engine and fuel system to cool before beginning work.
- Relieve fuel-system pressure according to the engine manufacturer's procedure and keep absorbent material available for residual fuel.
- Disconnect the old connector from the fuel tank and remove the hose clamp or retaining hardware.
- Confirm that the replacement connector matches the original connector and that the hose is 5/16 in (8 mm) where applicable.
- Install the connector onto the hose using a suitable fuel-line clamp. Do not damage, split, or excessively stretch the hose.
- Attach the connector to the compatible male tank fitting until it is fully seated and retained.
- Prime the fuel system according to the engine manufacturer's instructions and inspect the connection carefully for leaks before operating the engine.
Follow all applicable marine fuel-system safety requirements. If the hose, connector, or tank fitting is cracked, brittle, distorted, or leaking, replace the damaged component before use.
Troubleshooting & FAQ
How can I confirm that this is the correct connector?
Compare the old connector's shape, female tank-end configuration, retaining clip, hose connection, and hose diameter. Also compare the applicable manufacturer reference number. Engine brand or horsepower alone is not sufficient to confirm fitment.
Is this the tank-end or engine-end connector?
This listing describes a female connector for the fuel-tank end of the fuel line. Engine-end connectors may use a different design and should not be substituted without confirming the connection.
Does this connector fit a 3/8 in hose?
The listed application is for a 5/16 in (8 mm) hose. Do not install it on a 3/8 in hose unless the connector specifications and hose connection have been independently confirmed for that application.
Can I use the listed reference numbers as the only fitment check?
No. Reference numbers can help identify a replacement, but connector configuration, hose size, tank fitting, model details, and serial-number conditions should also be checked before ordering.
What are common signs that a fuel connector needs replacement?
Fuel odor, wetness or leakage around the connection, difficulty priming the fuel system, hard starting, engine stalling, cracks, brittleness, or a connector that does not lock securely are all reasons to stop using the component and inspect the fuel system.
Is this an OEM connector?
This listing is for an aftermarket replacement connector. It is not represented as a genuine Mercury or Mariner component.
Safety & Important Information
- Verify the original connector, hose size, tank fitting, and application details before ordering.
- Never operate an engine with a fuel leak or a connector that does not lock securely.
- Use only fuel-system-compatible hose clamps and components.
- Keep fuel away from flames, sparks, hot surfaces, and other ignition sources.
- Professional installation is recommended when the fuel system, hose, or tank fitting is damaged or difficult to access.
