Which statement about gas lines is true?

Which statement about gas lines is true?

• A. The gas line starts at the gas fill cap and terminates at the engine.
• B. The gas line starts at the engine and ends at the fill cap.
• C. The gas line must be completely nonmetallic.
• D. There is no requirement for gas line placement.

Answer: (A)

Fuel lines are designed to deliver gasoline from the storage tank to the engine. The tank is accessed through the fill cap, so the line is connected at the tank area (the fill cap region) and runs to the engine. That path ensures fuel moves from the source to the motor and is consistent with how the system is supposed to operate. The other ideas don’t fit because fuel should flow from the tank to the engine, not from the engine back toward the fill cap; fuel lines can be metal or flexible, not required to be completely nonmetallic; and there are placement and routing requirements to prevent leaks and hazards, not a lack of any requirement.
