Solution

1. Preparation

Tools Required: Safety goggles, gloves, fuel line wrench, OBD-II scanner, multimeter, smoke machine (if testing EVAP).
Park the vehicle in a well-ventilated area and ensure the engine is off and cool.
Disconnect the battery to prevent any electrical sparks.

2. Inspect Fuel Lines

Sub-steps:
1. Locate the fuel lines running from the fuel tank to the engine.
2. Use a flashlight to closely inspect for any visible cracks or fuel stains.
3. Replace any damaged lines using a fuel line wrench.

3. Check Fuel Injectors

Sub-steps:
1. Remove the engine cover if necessary to access the fuel injectors.
2. Inspect each injector for signs of leakage or damage.
3. Replace any faulty injectors with new ones, ensuring proper torque specifications are followed (usually around 15-20 ft-lbs).

4. Inspect Fuel Tank

Sub-steps:
1. Safely lift the vehicle with jack stands to access the fuel tank.
2. Visually inspect the tank for leaks, rust, or damage.
3. If leaks are detected, replace the fuel tank according to manufacturer specifications.

5. Examine Fuel Cap

Sub-steps:
1. Remove the fuel cap and inspect the rubber seal for any cracks or wear.
2. Replace the fuel cap if it does not create a proper seal.

6. Test EVAP System

Sub-steps:
1. Connect the smoke machine to the EVAP system at the designated port.
2. Activate the machine and observe for any smoke escaping from the system.
3. Repair or replace any components that show signs of leakage.
