    George,
If you have access to your tank, you can measure the width X length X height to get "gross cubic inches". divide by 231 to get gross gallons. Subtract 10% for construction and air space will get you real close. Fred

George,
Check the ground at the tank. The gauge reading is based on resistance to ground. Page 260 of your Owner's Manual states 130 gallons.
