Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent any electrical shorts.
2. Inspect and Repair Fuel Lines
  • Sub-steps:
    1. Locate the fuel lines running from the tank to the engine.
    2. Use a flashlight to inspect for cracks, corrosion, or loose fittings.
