I don’t think it does.

For each SCL in AirData » AirExecutionFactorsData » AirPackagesData is an element for Fuel. The design originally was that each SCL could “cost” a certain fuel burn rate (some munitions cause more drag than others). Envisioned in the original design was a provision that a certain SCL could have a negative fuel penalty (in other words, an SCL could possibly contain auxiliary fuel tanks). Neither one of these has been fully implemented.
