my Skoda Octavia NFL (2020-Present) has a strong smell of gasoline, what could be the issue?

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Lines (if necessary)

• Tools Required: Socket set, line wrench, fuel line disconnect tool.
• Sub-steps:
  1. Remove any protective covers to access the fuel lines.
  2. Use a line wrench to disconnect the fuel lines at both ends.
  3. Inspect the lines for cracks or wear; replace if damaged.
  4. Install the new fuel lines, ensuring they are secured properly.

3. Inspect and Replace Fuel Injector Seals (if necessary)

  4. Replace the old seals with new ones and reassemble the injectors.
  5. Reinstall the fuel rail and reconnect the electrical connectors.

4. Check and Replace Fuel Pressure Regulator (if faulty)

• Tools Required: Socket set, torque wrench, fuel pressure gauge.
• Sub-steps:
  1. Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
  2. Disconnect the vacuum line from the regulator.
  3. Remove the fuel pressure regulator from the fuel rail.
