Solution

1. Preparation

• Gather Tools and Materials: Ensure you have the following tools ready:
  • OBD-II scanner
  • Socket set
  • Torque wrench
  • Fuel line disconnect tool
  • Safety goggles and gloves
• Safety Precautions: Disconnect the battery to prevent any electrical shorts and allow the engine to cool before starting work on the fuel system.

2. Addressing Fuel Leaks

1. Fuel Line Replacement:

   • If leaks are found in the fuel lines, remove the damaged section using the socket set and fuel line disconnect tool.
   • Install new fuel lines, ensuring they are properly secured and torqued to manufacturer specifications.

2. Fuel Injector Replacement:

   • Remove the engine cover if necessary to access the fuel injectors.
   • Disconnect the electrical connectors and fuel lines from the injectors.
   • Replace any faulty injectors with new units, ensuring they are seated correctly and secured.

3. Fuel Tank Inspection and Repair:

   • If the fuel tank is damaged, carefully drain the fuel using a siphon pump.
   • Remove the fuel tank by disconnecting all necessary components (fuel lines, electrical connectors, etc.).
   • Repair or replace the fuel tank as needed, ensuring all seals and gaskets are replaced.
