DESCRIPTION
Some LH vehicles are equipped with a locking fuel
filler neck cap tethered to the fuel tank filler neck.

standard vehicle ignition key is used to lock or
unlock the fuel filler cap. By inserting and rotating
the ignition key to the right the cap is in the
“unlocked” position. Rotating to the left the cap is in
the “locked” position.
