I experimented with my pumps (from Tracy) by having them pump fuel from
floor level into a can on my bench. They self-primed and pumped the fuel up
about 3 feet quite happily. I did this multiple times before deciding to
mount them on the floor anyway.

Ha!  That's funny.

The more I've thought about it, the more I think I might just put them about
a foot high on the side wall.  If you think about it, they're mounted in the
top of a fuel tank on your car, and they do have to lift fuel some when
you're low.  Having two of them in parallel, drawing from the same tank, I'm
sure I'll have fuel if I need it.  

Bottom line is that I just don't want them on the floor. If the turbo
doesn't work out, I might have to move the battery forward into that area.
I also don't have a plan for a heater yet which might require that space.
There's also a dozen other perfect uses for it, including a place to stretch
out my legs.  Nope, the pumps are going on the side wall.

Ed- I can understand why you wanted the boost pump, but in my case, the
pumps and filters will all be in the cockpit, so there should be no chance
of boiling fuel unless the plane is on fire.  In that case, I'll either be
running for a fire extinguisher, or parachuting for safety, and hoping the
plane doesn't hit anything because I STILL don't have insurance.  

Thanks to all who commented.
