Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Identify Leak Source

Sub-steps:
1. Remove the fuel filler cap to relieve pressure in the fuel system.
2. Inspect the fuel lines from the fuel tank to the engine for any cracks, wear, or loose connections.
3. If a leak is identified, mark the area for repair.
