How do I fix a fuel leak where the filter connects to the fuel line?

To fix a fuel leak at the connection between the filter and the fuel line, first ensure the engine is off and allow it to cool. Inspect the connection for any visible cracks or damage, and tighten any loose fittings. If the leak persists, consider replacing the fuel filter or the fuel line as needed, ensuring you use compatible parts. Always check for proper sealing with new O-rings or clamps if needed, and ensure that all connections are secure before starting the engine.
