• Screwdrivers
• Fuel line disconnect tool
• Safety glasses and gloves

2. Inspect and Replace Fuel Lines

• Sub-steps:
  1. Use the socket set to remove any covers or shields obstructing access to the fuel lines.
  2. Visually inspect the entire length of the fuel lines for cracks or damage.
  3. If damage is found, use the fuel line disconnect tool to remove the affected section.
  4. Install new fuel lines, ensuring they are correctly routed and secured with clamps.
  5. Torque all fittings to the specifications provided in the service manual.

3. Check and Replace Fuel Injector Seals

• Sub-steps:
