Hyundai Palisade (LX2): Evaporative Emission Control System / Fuel Filler Cap
Description and operation
A ratchet tightening device on the threaded fuel filler cap reduces the chances
of incorrect installation, which seals the fuel filler. After the gaskets on
the fuel filler cap and the filler neck flange contact each other, the ratchet
produces a loud clicking noise indicating that the seal has been set.
