Process/Skill Questions:
- What are the most commonly used fuels in small engines?
- What has influenced fuel usage the most, historically: technology, economics, or politics?
- What are the functions of the individual components of a fuel delivery system?
- How do these components work together to filter and deliver fuel?
- What path does the fuel follow from the tank to the engine through each of these components?
