Which component is identified as a fuel vapor line or hose in the liquid fuel leak inspection?

• A. Fuel delivery and return lines
• B. Fuel filter
• C. Fuel vapor lines and hoses
• D. EVAP system valves

Answer: (C)

Fuel vapor lines and hoses are the parts that specifically carry gasoline vapors rather than liquid fuel. In a liquid fuel leak inspection, you’re looking for leaks in the paths that handle liquid fuel, but the item identifying a fuel vapor line or hose points to the components that transfer vapors as part of the EVAP system. The other options describe lines that carry liquid fuel (delivery and return lines), a filtration component in the liquid fuel path (fuel filter), or devices that control vapor flow (EVAP system valves). So the term that directly designates a line or hose for fuel vapors is fuel vapor lines and hoses.
