Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts.
2. Inspect Fuel Lines
  • Use a socket set to remove any protective covers.
  • Carefully inspect the fuel lines from the tank to the engine for cracks or signs of leakage.
  • If leaks are found, proceed to replace the damaged sections of the fuel line.
3. Check Fuel Injectors
  • Remove the engine cover if necessary using a socket set.
  • Inspect each fuel injector for signs of leakage around the seals.
  • If leakage is present, remove the faulty injector using a fuel injector puller and replace it with a new one, ensuring proper sealing.
4. Examine Fuel Tank
  • Safely raise the vehicle using a jack and secure it with jack stands.
  • Visually inspect the fuel tank for any visible cracks or rust.
  • If damage is detected, drain the fuel tank and remove it using a socket set. Replace with a new tank as per manufacturer specifications.
5. Inspect EVAP System
