Must have some system to get around the problem. It has wing tanks?
Or dos it feed to the engine out of a header tank which is in turn fed
by the wing tanks?

Yes, two wing tanks and a header tank in the engine compartment.

My bet is it also has pumps from the wings to the header and only draws
fuel from the header. Hence no sucking on an empty tank.
