I guess the fuel pressure test would be the obvious thing to do -- not exactly easy but I'll give it a try.

An exhaust leak wouldn't normally cause this kind of lean situation, right?

An exhaust leak large enough could allow more Oxygen to cause a false reading. My wideband read higher AFRs when I had a leak.
