warm fuel to the header, as opposed to the main tanks (giving it distance and
volume to cool). What's your take on that Ken? Also, when you said that on
further consideration you might just use after-market external pumps, do you
mean that and no header?

If you can find a place to put it, I really like the use of a header
tank with fuel returning to it. No management required and no concern
about injesting air when low on fuel!
I also like returnless EFI which has been on a number of cars such as
the Neon for about 10 years now. Such systems seem more common every
year and don't seem to have any hot start issues. Not sure but I think
the 40 ish psi rail pressure is enough to prevent fuel boiling when the
engine is shutdown.

One had the stock Sub fuel pumps mounted in the bottom of
the wing tanks, on removeable plates - worked great ! The
return line came up to the roof, with a valve to direct return
flow to left or right tank, to aid in load balancing. Ideally,
the return line is not at the top of the tank, so the fuel
doesn't fall, picking up air & static .... One nice thing
about this is there were no fuel valves needed - just turn on
the pump on the tank you wanted to feed from ! ;-)
