Other than StratOps p. 35, there's this piece of errata in the new TechManual pdf:
* Install Engine (p. 101)
Above “Hovercraft” insert the following new subsection:
Fuel Capacity and Range: Fuel consumption is not tracked in Total Warfare standard rules play, and fuel-using Combat Vehicles have their fuel automatically included in the mass of their engine, rather than needing to allocate weight for it. However, if you wish to calculate the range for Combat Vehicles with ICE and Fuel Cell engines, assume a fuel mass equal to 10% of the engine’s mass, as found on the Master Engine Table. Range is then calculated by using the Support Vehicle fuel rules (see p. 129), referencing the appropriate engine type (see p. 127).
