Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Fuel Lines

Locate the fuel lines running from the tank to the engine.
Use a socket set to loosen the mounting clamps and carefully inspect the lines for cracks or loose connections.
Replace any damaged fuel lines with OEM parts as needed.

Remove the engine cover if necessary (use a socket set).
Inspect the fuel injectors for signs of leakage around the seals.
If leakage is detected, replace the faulty injector(s) and ensure the new seals are properly seated.

4. Examine Fuel Tank

Safely lift the vehicle using jack stands to access the fuel tank.
Look for any signs of damage, rust, or leaking at the seams.
If a leak is found, replace the fuel tank with a new OEM tank.
