      • Do not use any tools to remove the quick connector.
      • Keep the resin tube away from heat. Be especially careful when welding near the tube.
      • Prevent acid liquid such as battery electrolyte, from getting on the resin tube.
      • Do not bend or twist the tube during installation and removal.
      • Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor, fuel filter, and fuel pump assembly.
      • When the tube or fuel level sensor, fuel filter, and fuel pump assembly is replaced, also replace the retainer with a new one (green colored retainer).
      • To keep the connecting portion clean and to avoid damage and foreign materials, cover them completely with plastic bags or something similar.
