Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, fuel pressure gauge, leak detection dye (if needed).
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical hazards.

2. Identify and Isolate the Leak

Sub-steps:
1. Use the OBD-II scanner to clear any existing codes and note down any related codes for reference.
2. Apply leak detection dye to the fuel system and use a UV light to identify the exact location of the leak if visual inspection fails.

3. Repair or Replace Damaged Components

Sub-steps:
1. If a damaged fuel line is identified, cut out the damaged section and replace it with a new fuel line, ensuring it is secured with appropriate clamps.
2. If the fuel injectors are leaking, remove the injector rail, replace the faulty injectors, and ensure proper sealing with new O-rings.
3. If the fuel tank is leaking, evacuate the fuel tank, remove it from the vehicle, and repair or replace it as necessary.

4. Reassemble and Test

Sub-steps:
1. Reassemble any removed components in reverse order of disassembly.
2. Reconnect the battery and turn the ignition on (do not start) to pressurize the fuel system.
3. Check for leaks at all repair points during this pressure test.
