Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Fuel Filler Cap

Remove the fuel filler cap.
- Check for cracks or damage; if present, replace the cap.
Reinstall or replace the cap ensuring it clicks securely.

3. Repair Fuel Lines

Identify the source of the leak from the fuel lines.
- If a leak is found, proceed to replace the affected section of the fuel line.
Disconnect the battery to prevent any electrical issues during the repair.
Remove damaged sections of the fuel line using a socket set.
Install new fuel line sections using proper hose clamps.
Reconnect the battery after repairs.

4. Service the EVAP System

Inspect the charcoal canister for damage or blockages.
- If damaged, replace the charcoal canister.
Test the purge valve with a multimeter to ensure it's functioning correctly; replace if necessary.
