Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel line disconnect tool, safety goggles, gloves, rags.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical sparks.

2. Locate the Leak

Sub-steps:
- Perform a visual inspection of the fuel lines, tank, and injectors.
- Use a flashlight to inspect hard-to-see areas for wetness or fuel vapor.

3. Repair or Replace Damaged Components

Fuel Lines:
- If lines are damaged, use a fuel line disconnect tool to remove them.
- Cut the damaged section out and replace it with a new fuel line, securing it with clamps.
Fuel Injectors:
- Remove the engine cover (if applicable) and disconnect electrical connectors from the fuel injectors.
- Unbolt and remove the injector rail to access the injectors.
- Inspect and replace any leaking injectors with new ones, ensuring proper sealing with O-rings.
Fuel Tank:
- If the fuel tank is leaking, support it with a jack and remove the mounting straps.
- Drain the fuel and disconnect the fuel pump assembly.
- Inspect for cracks; if found, replace the entire tank. If minor, consider using a fuel tank repair kit.

4. Reassemble Components

Reinstall all components in reverse order of removal.
Ensure all connections are secure and use a torque wrench to tighten bolts to manufacturer specifications.

5. Final Checks

Reconnect the negative battery terminal.
Turn the ignition to the ON position without starting the engine to pressurize the fuel system and check for leaks.
