Inspect the fuel filler cap for damage or improper sealing, which could lead to evaporative emissions issues.
3
Check the fuel pressure using a fuel pressure gauge to determine if the fuel pump is delivering adequate pressure.
4
Inspect the fuel lines for leaks or damage, particularly around the area where fuel was added.
5
Examine the EVAP system components, including the charcoal canister and purge valve, for blockages or malfunctions.

Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening any fuel system components.

2. Replace Fuel Filler Cap

Ensure the fuel filler cap is the correct type for your vehicle.
Remove the old cap and install a new one, ensuring it clicks securely into place.

3. Repair or Replace Fuel Lines

Sub-steps:
- If leaks are found, identify the damaged section of the fuel line.
- Use a socket set to disconnect the fuel lines from the connectors.
- Replace any damaged sections with OEM or equivalent parts.
- Reconnect the fuel lines and ensure they are secured tightly.

4. Inspect and Repair EVAP System

Sub-steps:
- Remove the charcoal canister and inspect for cracks or blockages.
- If damaged, replace the charcoal canister with a new one.
