Description

The ratchet tightening device on the threaded fuel tank cap reduces the chance of improper installation, which results in sealing of the filler neck. When the gasket on the fuel tank cap and the filler neck flange make contact, the ratchet produces an audible click, indicating that the seal is installed.
