4. Tighten by hand until snug, then give an additional quarter turn to secure the lock without over‑tightening.
5. Check for leaks around the seal and verify that the fuel line is properly connected.
6. Start the engine and observe the filter housing for any signs of leakage or abnormal pressure readings.

Maintenance Tips

• Inspect the filter regularly, especially after long periods of operation or exposure to dusty environments.
• Replace the filter according to the manufacturer’s recommended interval or sooner if you notice a drop in fuel pressure.
• Keep the surrounding area clean to prevent debris from entering the filter housing during installation.
