Morphology
The meaning 'the amount of fuel remaining' is directly derivable from combining 'fuel' (material burned/consumed for energy) with 'level' (a measured amount or quantity). This is a regular noun-noun measurement compound that follows transparent compositional patterns found across languages, so a B1 learner who knows both words will readily understand it.
Etymology
Fuel level comes from a simple, literal image: the amount of fuel in a tank is like the level of water in a glass. Early gauges and floats showed how high the fuel sat, so the phrase came to mean the 'amount of fuel' left in the tank.
