Anyone know how to get the fuel gauge with a Fuel Cell to read correctly?

I have the 95 22 gallon Fuel Safe fuel cell. The sending unit still only reads like it was a 15.2 gallon tank. It says on on E and I still have 7 gallons left.

Thanks,
Ed

I thing aeromotive might have an upgraded sending unit, may want to talk to them.
