Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fuel pressure gauge, OBD-II scanner, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on the electrical system. Work in a well-ventilated area to avoid inhalation of fumes.

2. Locate and Repair Fuel Leaks

Lift the vehicle using jack stands for access to the undercarriage.
Visually inspect all fuel lines, connections, and the fuel tank for any signs of leaks.
If a leak is found in a fuel line, replace the damaged section using new fuel line and clamps.
If the fuel tank is leaking, it may need to be replaced or repaired, depending on the severity of the damage.

3. Replace Faulty Components

If the fuel pressure gauge indicates low or excessive fuel pressure, check and replace the fuel pump if necessary.
Inspect and replace any damaged or cracked hoses in the evaporative emissions system.
Ensure the fuel filler cap is properly sealed. Replace it if it is damaged or not sealing correctly.

4. System Testing

Reconnect the battery.
Start the engine and let it idle for a few minutes while monitoring for any gasoline smell or leaks.
Test the vehicle under various driving conditions to ensure the issue has been resolved.
