Fuel level sensors, removing and installing: Notes

NOTE:
  • Follow safety precautions and rules of cleanliness when working on fuel tank. See SAFETY PRECAUTIONS WHEN WORKING ON FUEL TANK  and RULES OF CLEANLINESS  .
  • Before both fuel level sensors are removed, check them with a multimeter (Fluke 83 or equivalent) to see if their resistance values are in an appropriate range for the level displayed on the fuel gauge. Since the fuel level sensors are connected in series, the two resistance values must be added together when checking them against the fuel gauge reading.
