fuel caps

Gas tank lids

Fuel caps are the covers that seal a vehicle's fuel tank opening.

They prevent fuel from spilling or evaporating and keep contaminants out.

Most screw on or click into place: The check engine light came on because the fuel cap was loose.

Also called gas caps in American English.
