Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the negative battery terminal to prevent electrical shocks.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.

2. Identify the Leak Source

Fuel Lines:
- Inspect all visible fuel lines for cracks or loose connections.
- If damaged, replace with OEM fuel lines.
Fuel Tank:
- Remove the rear access cover to inspect the fuel tank.
- If the tank is leaking, it may need to be replaced.
Fuel Injectors:
- Remove the engine cover and inspect the fuel injectors for leaks.
- Replace any faulty injectors with new ones.

3. Repair or Replace Components

For Fuel Lines:
- Use a line cutter to remove damaged sections and install new lines using appropriate fittings.
- Torque fittings to the manufacturer’s specifications (usually around 15-20 Nm).
For Fuel Tank:
- If replacement is necessary, remove the tank by unbolting it from the chassis and disconnecting all fuel lines.
- Install the new tank and reconnect all lines and bolts.
For Fuel Injectors:
- Carefully remove old injectors from the fuel rail.
- Install new injectors with the correct O-rings and torque to specifications.

4. Reassemble and Test

Reconnect the fuel pump relay and the negative battery terminal.
Start the engine and check for leaks around all repaired areas.
Ensure the check engine light is cleared if applicable.
