Perhaps I should have been more specific. Smaller openings under equal
pressure will move fluid faster than a pipe with a larger diameter. Add to that the
shorter run of the smaller pipes. I don't want to get into discussion about
Poiseuille's law and other matters esoteric relative to Vanagon maintenance.
There is another time and place for that. I'd like to keep discussions to a level
that most people understand. (Don't Killer Juniper jumping in saying I am not
smart enough to know how to prune shrubs.)

Nothing is ever absolute as far as I am concerned (except a certain Vodka).
You can plug your heater hoses together and not have any problems at all. What
I am saying is you are more likely to encounter problems with the arrangement
that you propose instead of simply plugging the hoses.

So small short hose vs. long large hose. Fluid, fluid where shall you go. You
can go faster in the small one. Slower but in larger volume in the big pipe.
Oops! Your still flowing in the big pipe but some of you have taken the
shortcut via a new bypass through a much shorter pipe. Yeah, that's the ticket.
Short run and turn around. No laminar flows and viscosity considerations. We'll,
just ignore the effect of gravity too. Not significant enough. Leaving that to
Killer Juniper.
