If I use Rampant Arsenal 1.1.6 with Space Exploration 0.6.112 and Krastorio 2 1.3.22 (all at their latest version as of now), the nuclear car will only work with AAI's processed fuel, and Krastorio's fuels: fuel, biofuel and advanced fuel.
I'm not sure if those mods should be taking the care so they don't overwrite settings for cars that already work.
