Leakage Inspection

  1. Press RESET switch to set left display reading to 0.0.

  3. Turn control valve to FILL position.
  4. Wait (maximum 20 seconds) until left display reads 13.9-14 inches of water. If reading is slightly below, adjust it using regulator knob. If reading is far below, fuel-filler cap has leak. Replace fuel-filler cap.
