Have we considered the easiest explanation?

Was there a header tank?

Did we ever determine if the header tank ran dry?

Wasn't the last leg of the flight just over an hour and isn't that just about the time that the header would run out of fuel?

Usually the simplest theoretical explanation for a given set of sensually perceivable phenomena is considered to be the correct answer.
