Use a socket set to remove any protective covers.
Visually inspect fuel lines for cracks, wear, or leaks.
If leaks are found, replace the damaged sections of the fuel line with OEM parts.

3. Check Fuel Injectors

Remove the engine cover (if applicable) using a socket set.
Inspect each fuel injector for signs of leakage or damage.
Replace any faulty injectors with new ones, ensuring to use proper torque specifications (usually around 15-20 Nm).

4. Examine the Fuel Tank

Safely lift the vehicle using a jack and secure it with jack stands.
Inspect the fuel tank for cracks or corrosion.
If damage is found, drain the tank and replace it with a new one, ensuring to use the correct fuel type.
