Solution

1. Preparation

Gather all necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Fuel Lines

Use a socket set to remove any protective covers if necessary.
Visually inspect all fuel lines from the tank to the engine for cracks or signs of wear.
Tighten any loose connections if found; replace any damaged lines.

3. Replace Fuel Injector Seals

Remove the engine cover if applicable.
Disconnect the fuel injector electrical connectors and fuel supply line.
Remove the fuel injectors and inspect the rubber seals for damage.
Replace the seals with new ones, applying a small amount of engine oil for lubrication.
Reinstall the injectors and reconnect all electrical connectors.

4. Check Fuel Pressure Regulator

Locate the fuel pressure regulator on the fuel rail.
Disconnect the vacuum line from the regulator and inspect for fuel leakage.
If leakage is present, replace the fuel pressure regulator.
Reconnect the vacuum line and ensure all connections are secure.

5. Examine the Fuel Tank

Safely lift the vehicle using a jack and secure it with jack stands.
Inspect the fuel tank for any visible signs of damage or corrosion.
If damage is found, drain the fuel and replace the tank as necessary.
