The uphill one will still suck air. Usually this wouldn't be a too much of
a problem on a gasoline vehicle as there is a 3.5BAR fuel pump there that
would go a reasonably good job of squeezing out the air and you may feel the
occasional stumble in the motor. On a Diesel motor, the injector pump sucks
the fuel from the tank so air bubbles are a little more of a concern.

David,
Just "thinking" of course: would it be possible to run a line out of each
end of the tank, into one line to the fuel pump?
