As I've found out today, Per-Player mod settings would not let me be able to determine what new fuels and ammunition would be added by other mods at the time the settings are done. While this idea is nice, it's unfortunately not a perfect fit. I have added a different option to limit the fuel/ammo based on the value/damage it has, so that nuclear fuel and uranium fuel cells can be ignored because they're too potent for Fill4Me. It's not perfect either, but it does let Fill4Me work nicely with other mods while usually achieving the same goal.
