How often should I change this fuel filter?

You should always follow the service interval recommended by your vehicle manufacturer in the owner's manual.

Can I reuse this filter after cleaning it?

Troubleshooting

Engine hard to start after replacement

Ensure the fuel system was properly primed and all air bubbles were purged from the fuel lines after installation.

Leakage at the filter base

Verify the old gasket was fully removed and the new gasket is properly seated; check that the filter is tightened to manufacturer specifications.

Filter is stuck during removal

Use an appropriate oil/fuel filter wrench to provide better leverage; ensure you are turning counter-clockwise.
