Solution

1. Preparation

Tools Required: Wrench set, OBD-II scanner, fuel pressure gauge, cleaning rags, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Repair Fuel Lines

Sub-steps:
1. Locate the fuel lines running from the fuel tank to the engine.
2. Visually inspect the lines for cracks, abrasions, or loose fittings.
3. Tighten any loose connections with the appropriate wrench.
4. If a leak is found, replace the damaged section of the fuel line with OEM parts.

3. Inspect and Repair Fuel Tank

Sub-steps:
1. Safely elevate the vehicle using jack stands if necessary.
2. Inspect the fuel tank for any signs of damage or corrosion.
3. If a crack or hole is found, replace the entire fuel tank.
4. Ensure all seals and gaskets are replaced during installation.

4. Test Fuel System Pressure

Sub-steps:
