I believe that on the inside monitor panel is were that tanks reading is.
Thanks DesertRat I found it...
I was told it was on the inside monitor panel during my PDI but I was looking for an analog gauge. I found the small Gen Fuel button for the generator fuel level that lights up on the display for the fresh/black/grey tank levels.
