I don't know if fixing the Electric Train 2.0 Fix fuel situation is quite in scope for this mod since that mod just has a script it uses to fill its locomotives on fuel every tick, but the other fuels not copying over is definitely a problem I'm having. Since you're not running into it, I would tend to assume that another mod is causing problems, but unless Automatic Train Painter, Vehicle Equipment Grids, or K2 are causing it, I don't know.
