Good point for the general populous. I forgot that I was predicting the
behavior of my system with the Yamaha peculiarity (at least on the QM
series) of there being no return line to the tank. Return fuel is pumped
back around to ahead of the injector pump so there is no way to suck air
back into the system unless there is a leak in the piping.

Just following up on your "heeling 20 degrees comment": Athough true,
it is not nearly as vigorous as a day or two of bounding through some
serious waves. That will dislodge a lot more tank sediment than
normal heeling and tacking.
