- Ensure the engine is off and the fuel system is depressurized. Always work in a well-ventilated area away from any potential ignition sources.
- For the tank connection, thread the male connector (with its pre-applied sealant) onto the 1/4" NPT fitting on your fuel tank. Tighten securely but do not overtighten.
- For the hose connection, attach the female connector to your 3/8" or 5/16" fuel line, securing it with an appropriate hose clamp (not included).
- Connect the male and female fittings by pushing them together until they click firmly into place, ensuring a secure lock.
- After installation, prime the fuel system using your engine's primer bulb and meticulously check for any fuel leaks at all connection points before starting the engine.
Troubleshooting & FAQ
Will this connector fit my specific engine brand (e.g., Yamaha, Mercury)?
Yes, this Universal Sprayless Connector is designed to be fully compatible with all OEM marine engine brands from 1HP to 350HP, as well as all standard marine fuel tanks that use a 1/4" NPT fitting.
How does this prevent fuel spray?
The connector features recessed check valves that automatically seal the fuel line when disconnecting and prevent accidental spray if bumped. This design ensures fuel is contained within the line, providing a safer user experience.
Can I buy just the male or female part?
This product is sold as a complete set including both male and female connectors. However, individual components can be sourced separately. The male tank connector is equivalent to Attwood 8838TM6, and the female hose connector is equivalent to Attwood 8838HF6.
Is this connector resistant to ethanol-blended fuels?
Absolutely. It is constructed from a high-strength, fuel-resistant POM plastic, making it fully compatible with modern gasoline and ethanol-blended fuels without degrading over time.
What are signs that my sprayless connector needs replacement?
Signs of failure include persistent fuel leaks at the connection point, difficulty connecting or disconnecting the fittings, or visible cracks, and damage to the plastic housing. Regular inspection is recommended for safety.
