Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative terminal of the battery to ensure safety.
  • Allow the vehicle to cool if it has been recently operated.
2. Access Fuel Sending Unit
  • Tools Required: Socket set, screwdrivers
  • Raise the vehicle and safely support it on jack stands.
