Fuel Tank Location

Anyone know the rules/regs on installing fuel tanks for a oil stove. There are two tanks tied together crammed under this unique roof overhang.

They should be the same as if they are installed in a basement/crawlspace. What does your local AHJ have to say about it?

Is it ULC listed and fuel oil? What about it’s age? It doesn’t look like it has a vent pipe extending above the fill pipe or a whistle. Basically it doesn’t look like something that would be accepted in my location, but the rules may be different in yours.
