Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Fuel Filler Neck

Remove the fuel cap and visually inspect the filler neck for cracks.
If damaged, remove the screws securing the filler neck and detach it from the tank.
Install a new fuel filler neck, ensuring all connections are tight.

3. Check and Replace Fuel Lines

Inspect for any visible leaks or deterioration.
If leaks are found, use a wrench to disconnect the damaged line and replace it with a new line.
Secure connections with appropriate clamps.

4. Examine and Replace Fuel Cap

Remove the fuel cap and inspect the rubber gasket for wear or damage.
If the gasket is worn, replace the fuel cap with a new OEM cap to ensure proper sealing.
