- Carefully relieve any pressure from the fuel system before disconnecting old fittings.
- Unscrew the old male connector from the fuel tank.
- Clean the tank's threaded port to ensure a clean surface for the new sealant.
- Screw the new Universal Sprayless Connector into the tank. The pre-applied sealant makes additional tape unnecessary.
- Tighten by hand first, then use a wrench for a final quarter-turn. Do not overtighten, as this can damage the plastic housing or tank threads.
- Connect your fuel hose securely and check for any leaks before starting the engine.
Troubleshooting & FAQ
Will this connector fit my specific outboard model?
This is a universal connector designed to fit any outboard brand—including Mercury, Yamaha, Honda, Suzuki, and Johnson/Evinrude—that uses a standard 1/4" NPT fuel tank fitting. Please verify your tank's thread size before ordering to ensure compatibility.
How does the "sprayless" feature work?
The connector contains an internal check valve. This valve automatically seals the opening when the fuel line is disconnected, preventing pressurized fuel from spraying out. This creates a safer and cleaner environment during refueling and maintenance.
Do I need to add thread sealant or Teflon tape for installation?
No. The connector comes with a pre-applied coating of fuel-grade thread sealant. This is designed to create a secure, leak-free seal upon installation without any additional products.
What are the signs of a failing fuel tank connector?
Common signs include visible fuel leaks around the fitting, a strong smell of gasoline, difficulty connecting or disconnecting the fuel line, or air getting into the fuel system (which can cause poor engine performance, stalling, or hard starts).
