I believe your bottom picture in the post is the correct orientation for everything. All you need now is the little spring that goes onto the jack handle and runs up to the ratchet of the mast. The ratchet control is in the "lower" orientation in the picture. Once you have the spring on, turn the control to "raise" and manually run the ratchet up until there's tension on the spring. I think that will also bring you up high enough that the hook will be tight against the fuel filler pipe, otherwise the hook will chatter and carry on while the car is in motion.
