Works with vanilla and modded inserters. Does not add or modify prototypes.
Inserters leech from anything that has a burner. They do not leech if they or their drop target do not need fuel.
If you want to use burner inserters for anything else than smelter input, cascade burner tech (example: ore to steel), or want to be able to leech fuel from vehicles into burner tech - this mod is for you.
