Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, flashlight, absorbent cloths, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical accidents.

2. Inspect Fuel Lines and Connections

Use a flashlight to thoroughly inspect the fuel lines along their entire length.
Check all connections and fittings for tightness; tighten any loose connections.
If any lines appear damaged, proceed to replace them.

3. Inspect and Replace Fuel Injectors (if needed)

Tools Required: Socket set, torque wrench.
Remove the engine cover to access the fuel rail.
Use a socket set to remove the bolts securing the fuel rail.
Carefully disconnect the fuel injectors from the rail and inspect the seals.
Replace any damaged injector seals and reinstall the injectors, ensuring they are seated correctly.

4. Check Fuel Tank for Leaks

Safely raise the vehicle with jack stands to access the fuel tank.
Inspect the fuel tank for any visible cracks or corrosion.
If a leak is found, the tank will need to be replaced. Remove the tank by disconnecting fuel lines and electrical connections, then unbolt it from its mounts.

5. Confirm Repairs and Reassemble

After addressing the leaks, reassemble any removed components in the reverse order.
Ensure all connections are secure and reattach the battery.
