fuel cap

Gas tank cover

A fuel cap is the removable cover that seals a vehicle's fuel tank opening.

It prevents fuel from spilling or evaporating and keeps contaminants out.

Most modern fuel caps click when properly tightened; a loose or missing cap can trigger a check engine light.

Also called a gas cap.
