Well there you go. Another potential conspiracy and cover-up blasted away. It appears Boeing simply made an error in accounting for their documentation. Can you imagine such a thing?
1980 study on fuel pump performance in the E-4B. The 19-year-old report on fuel tank heating in a military version of the Boeing 747 was prepared for the U.S. Air Force.
It was a document about fuel pump performance that in retrospect bears a resemblance but, by the way, has to do with a configuration that is entirely different (than a commercial 747) under a different use. It would not have changed the outcome of the investigation.
