Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical sparks.
Gather tools and parts needed for the repair.

2. Identify the Leak Source

If the leak is found in the fuel lines:
- Sub-step 1: Remove any protective covers or shields to access the fuel lines.
- Sub-step 2: Replace damaged sections of the fuel line using appropriate tubing.
- Sub-step 3: Secure connections with hose clamps and ensure there are no kinks.
If the leak is from the fuel injectors:
- Sub-step 1: Remove the engine cover if applicable.
- Sub-step 2: Disconnect the fuel injector connectors and remove the fuel rail.
- Sub-step 3: Inspect and replace faulty O-rings on the injectors.
- Sub-step 4: Reassemble the fuel rail and reconnect the injectors.

3. Reassemble and Test

Sub-step 1: Reattach any components that were removed for access (like the engine cover).
Sub-step 2: Reconnect the negative battery terminal.
Sub-step 3: Turn the ignition key to the ON position to pressurize the fuel system without starting the engine.
Sub-step 4: Inspect for any leaks during this pressurization.
