Fuel Filler Cap: Description and Operation
OPERATION
The fuel tank filler neck is equipped with a screw type cap. The threaded part of the cap requires several turns counterclockwise to remove. The
long threaded area was designed to allow any remaining fuel tank pressure to escape, while the cap is being removed. A built-in torque-limiting
device prevents overtightening. 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.
