Description and Operation

Description

A ratchet tightening mechanism on the threaded fuel tank cap reduces the possibility of incorrect installation, which could lead to a fuel filler neck seal failure. When the gasket on the filler cap and the filler neck flange contact each other, the ratchet makes a loud clicking sound, indicating that the seal is installed.
