Morphology
The literal meanings of 'empty' (remove all contents) and 'tank' (a container) give a clear clue that something is being used up, so a B1 learner could plausibly infer a metaphorical sense of using all resources in context. However, the extension of a physical container to mean a person's energy or stamina is figurative and not guaranteed to be predictable without prior exposure, so the expression is only partially transparent.
Etymology
Empty the tank comes from the simple action of opening a valve and letting all the fuel or water flow out of a tank. So, it means 'to remove all the contents'.
