Instructions for Operation

  1. Unthread the red locking nut. Separate the aluminum bushing from the rest of the gauge. (do not lose the rubber gasket)
  2. Thread the aluminum bushing into the female fitting on the top of your tank.
  3. Drop gauge through the center of the aluminum bushing float first. Be sure your gasket is still in between the top of the bushing and the calibration.
  4. Be sure your swing arm is pointing to an open spot in the tank, avoiding walls, corners, baffles or other obstructions.
  5. Tighten your red locking nut and calibration down to the aluminum bushing. Hand tighten the red nut until snug. If a tool is required, use care not to break the red nut
