1. Preparation

Tools Required: Safety goggles, gloves, socket set, OBD-II scanner, rags.
Park the vehicle on a flat, safe surface and allow it to cool.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Inspect Fuel Lines

Remove any protective covers if necessary.
Visually inspect the fuel lines from the fuel tank to the engine for any cracks or fuel seepage.
If a leak is found, replace the damaged fuel line using a socket set.

3. Check Fuel Tank

Safely lift the vehicle using jack stands.
Inspect the fuel tank for any visible rust, punctures, or leaks.
If damage is found, replace the fuel tank following these sub-steps:
- Drain the fuel tank.
- Disconnect all lines and electrical connections.
- Remove mounting bolts and carefully lower the tank.
- Install the new fuel tank by reversing the removal steps.

4. Examine Fuel Injectors

If an injector is leaking, remove it using a socket set and replace it with a new one.
Ensure to use new O-rings to prevent future leaks.

5. Inspect EVAP System

Locate the EVAP canister and inspect for any cracks or loose connections.
Use a smoke machine to test for leaks in the EVAP system.
If a leak is detected, replace the faulty component (e.g., canister, hoses).
