Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical sparks.

2. Inspect Fuel Lines

Tools Required: Socket set, flashlight.
Visually inspect the fuel lines for any signs of wear or leaks.
If damage is found, replace the affected sections of the fuel lines.

3. Check Fuel Injectors

Tools Required: Torque wrench, fuel injector O-ring kit.
Remove the engine cover (if applicable) to access fuel injectors.
Inspect the O-rings for wear or damage; replace if necessary.
Reinstall injectors and torque to manufacturer specifications.

4. Examine the Fuel Tank

Tools Required: Floor jack, jack stands, wrench set.
Safely lift the vehicle and support it with jack stands.
Inspect the fuel tank for any visible leaks or corrosion.
If leaks are found, replace the fuel tank; if corrosion, treat or replace accordingly.
