How is "motor fuel container" best defined?

The definition of "motor fuel container" specifically pertains to a container designed to hold fuel that is used to power the engine of a vehicle. This definition captures its essential purpose, which is to store the fuel necessary for operation, making it a fundamental component for vehicles that rely on liquid fuels, such as liquefied petroleum gas, gasoline, or diesel.

Choosing a container that "propels the vehicle's engine" emphasizes its role in providing the energy source required for the engine's operation, delineating it from other types of containers that serve entirely different functions. For instance, a container for storing food, holding water, or a storage unit for emergency tools has no relation to vehicle operation, thereby clearly illustrating the specific utility of a motor fuel container in transportation.
