Fuel Tank: Inspection

INSPECT FUEL TANK ASSEMBLY WITH FUEL PUMP
1. Measure the resistance between terminals 3 and 7.
  Standard resistance: 0.2 to 3.0 Ω at 20°C (68°F)
  
  If the resistance is not as specified, replace the fuel tank assembly.

2. Check that the motor operates when battery voltage is applied across the terminals.
  NOTE:
  - Perform the check quickly (shorter than 10 seconds).
  - Keep the battery as far away the fuel tank as possible.
  - Always turn the voltage on and off on the battery side, not the fuel tank side.
  If the motor does not operate, replace the fuel tank assembly.
