4. Apply a small amount of engine oil to the new seals before installation.
5. Reinstall the injectors and reconnect the fuel lines.

4. Inspect and Replace Gas Cap

Sub-steps:
1. Remove the gas cap and inspect it for cracks or a damaged rubber seal.
2. If damaged, replace it with a new OEM gas cap.
3. Ensure the new cap clicks securely to create a proper seal.

5. Test the EVAP System

Sub-steps:
1. Use an OBD-II scanner to run a diagnostic test on the EVAP system.
2. If any faults are detected, inspect components like the purge valve and charcoal canister for damage.
3. Replace any faulty components as necessary.
