1. Lift the vehicle using jack stands if necessary.
2. Visually inspect all fuel lines for cracks, corrosion, or loose connections.
3. If any damage is found, replace the affected sections of the fuel line.
4. Use fuel line clamps and appropriate connectors to secure new lines if needed.

3. Check and Repair Fuel Tank

Sub-steps:
1. Inspect the fuel tank for signs of rust or pinholes.
2. If a leak is detected, remove the tank by disconnecting the fuel pump wiring and fuel lines.
3. Repair minor leaks using a fuel tank repair kit, or replace the fuel tank if severely damaged.
4. Reinstall the tank, ensuring all connections are tight.

4. Examine Fuel Injectors

Sub-steps:
1. Remove the engine cover if necessary to access the fuel rail.
2. Check each fuel injector for leaks around their seals.
