7. Troubleshooting
This section addresses common issues you might encounter with your fuel tank fitting.
| Problem | Possible Cause | Solution |
|---|---|---|
| Fuel Leak at Hose Connection | Loose hose clamp, damaged hose, or improperly seated hose. | Tighten hose clamp, inspect hose for damage and replace if necessary, ensure hose is fully seated on the barb. |
| Fuel Leak at Tank Connection | Fitting not fully engaged with tank connector, damaged O-ring (if applicable), or incompatible tank connector. | Ensure fitting is securely locked onto the tank connector. Inspect the tank connector for damage. Verify compatibility with Mercury/Mariner tanks. |
| Poor Fuel Flow | Obstruction in the fitting or hose, or a problem elsewhere in the fuel system. | Inspect the fitting and hose for blockages. If the fitting is clear, troubleshoot other components of the fuel system (e.g., fuel filter, fuel pump). |
If troubleshooting steps do not resolve the issue, discontinue use and contact Attwood customer support or a qualified marine technician.
