If the tanks are plain old rectangular boxes, some simple math should figure it out. Odd shapes; kick the math up a notch.
Barring that, you can always check each stick before and after adding fuel, then do the simple math method. That should at least tell you gallons per mark on the stick.
Keep in mind though, "0" won't be the bottom and "12" likely not the top.
