Fuel Filler Cap: Description and Operation
COMPONENT DESCRIPTION
The fuel tank filler neck is equipped with a screw type cap. The threaded part of the cap requires several turns counter-clockwise to remove. The long
threaded area is designed to allow any remaining fuel tank pressure to escape during the cap removal operation. A built-in rachet type 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. A fuel filler cap that is not fully seated, may cause a malfunction in the emission system.
NOTICE: If a fuel filler cap requires replacement, only a cap with the same features should be used. Failure to use the correct cap can result in a serious
malfunction of the system.
