A lot depends upon the fuel pump being strong enough. It may not be, or it may simply not last long. Was your inboard also a gasoline engine? Beware of gasoline fumes in the bilge if not!! Even if gravity and proximity make the aft compartment a better place to store fuel, fumes from there can also be explosive. A bilge fan, run for a number of minutes before starting the motor, is an important safety procedure.
