Why, is because the internal storage doesn't seem to see it as a valid fuel source (probably because the container doesn't get "burned up" as well).
Please test this, as I haven't tested this issue thoroughly, and it turns out it does function as a valid fuel source, and my suggestion below is already implemented.
Suggestion(s):
Maybe make the empty rods dump into the mecha's inventory.
You have my permission to close it without my knowledge if I'm full of baloney :P.
