Every centrifugal pump used to pump volatile liquids that I've seen has had a bypass/re-circulation system. If you deadhead a centrifugal pump, heat is generated in the bowl and the liquid being pumped can flash. But I've never taken an electric fuel pump apart, so I can't swear that they follow the "rule." The FSM may have an exploded drawing or you may be able to suss out the info from the piping diagrams and descriptions.
