my Skoda Octavia NFL (2020-Present) has a strong smell of fuel, what does this mean?

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to avoid any electrical issues.

2. Inspect and Repair Fuel Lines

• Tools Required: Socket set, wrench set, fuel line removal tool.
• Sub-steps:
  1. Locate the fuel lines running from the fuel tank to the engine bay.
  2. Visually inspect the lines for cracks, wear, or loose connections.
  3. If leaks are found, use the fuel line removal tool to disconnect the damaged sections.
  4. Replace any damaged lines with new, manufacturer-approved fuel lines.
  5. Reconnect the lines and secure them properly.

3. Check and Replace Fuel Injectors

• Tools Required: Torque wrench, injector puller (if necessary).
• Sub-steps:
  1. Locate the fuel rail and remove the necessary engine covers.
  2. Disconnect the electrical connectors from the fuel injectors.
  3. Unbolt and carefully remove the fuel rail.
  4. Inspect the injectors for leaks and cleanliness; replace any that show signs of failure.
  5. Reinstall the fuel rail and secure it with the specified torque setting.

4. Inspect the EVAP System

• Tools Required: Smoke machine (for leak testing), basic hand tools.
• Sub-steps:
  1. Locate the EVAP canister and associated hoses.
