Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical sparks.

2. Inspect and Repair Fuel Lines

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the fuel lines running from the fuel tank to the engine.
3. Inspect each fuel line for cracks or leaks.
4. If a leak is found, replace the damaged section of the fuel line.
  - Tools Required: Wrenches, hose clamps.
  - Parts Required: Replacement fuel line, hose clamps.

3. Check and Replace Fuel Injectors (if necessary)

Sub-steps:
1. Remove the engine cover, if applicable, to access the fuel injectors.
2. Disconnect the electrical connectors from the injectors.
3. Remove the retaining clips and carefully pull the injectors out of the intake manifold.
4. Inspect the O-rings on the injectors for wear; replace them if damaged.
5. If injectors are leaking, replace them with new units.
  - Tools Required: Socket set, injector puller (if necessary).
  - Parts Required: Replacement fuel injectors, O-rings.

4. Fuel Tank Inspection and Repair

Sub-steps:
1. If leaks are suspected from the fuel tank, drain the fuel tank (use a siphon if necessary).
2. Remove the fuel tank from the vehicle (disconnect fuel lines and electrical connections).
3. Inspect the tank for any cracks or corrosion; repair with a suitable sealant if minor, or replace if extensive damage is found.
  - Tools Required: Socket set, fuel tank strap wrench.
  - Parts Required: Fuel tank sealant or replacement tank.

5. Reassemble and Test

Sub-steps:
1. Reinstall all components in reverse order of disassembly.
2. Reconnect the battery.
3. Start the engine and check for leaks around repaired areas.
