The shepherd's hook looking thing? That isn't a lever, that is at the tank breather with a loop to prevent rain from getting in. It does look like something you'd pull but it you take a second look it is held on with a hose clamp and although painted, it is made out of a soft, rubbery material.
In #4 right above the vent. It looks like a spool with maybe a U bracket with a pin going thru it. What is that for?
