During fueling, what should you do with the fuel cap?

• A. Leave the fuel cap loose
• B. Keep the fuel cap off during fueling
• C. Replace the fuel cap tightly
• D. Remove the fuel cap during fueling

Answer: (C)

You should replace the fuel cap tightly after fueling. The cap seals the fuel system and is part of the vehicle’s evaporative emissions and venting setup. A tight cap prevents gasoline vapors from escaping, reduces fire risk, and stops contaminants from entering the tank. It also helps maintain proper pressure in the fuel system and prevents spills or splashes while you’re driving. Leaving the cap loose, keeping it off, or removing it during fueling would allow vapors to escape, increase fire and contamination risk, and can lead to fuel spills.
