Better to plumb the pumps so that they can be run together in

enough when you're already busy.

Good point, I'm going to rig up two pumps and see if the pressure is not
too  high with both on, seems to work for Ed.

BTW, my "footer" tank is on the engine side of the firewall, top of the
tank is just below the main tank sumps.  The height of the tank is 6 inches,
and  the bottom inch or so is in the airstream of the big naca inlet (on the
fuselage bottom) to the radiators.  This should have the effect of keeping
that tank and it's contents cool.  Will probably make my new tank of steel
though, as I said before (crash and fire resistance).

To put it on the fuselage side of the firewall, it would have to go
under the passenger seat, not too crazy about that either, and it's a difficult
place to get to.  It would also not be a very big tank in that area, and would
not get  any cooling air.
