Fuel Filler Cap: Description and Operation
The fuel tank filler neck is equipped with a threaded-type cap. The threaded part of the cap requires several turns counterclockwise to remove. A built-in
torque-limiting device prevents over tightening. To install, turn the cap clockwise until a clicking noise is heard. This signals that the correct torque has
been reached and the cap is fully seated.
