See my other post on the TPI for Jag thread.
I think the six-port valve from JC-Whitny is the simplest solution.  Mine was 
overly complex because I was using "free" parts.
But to sum up:  I had the original submerged fuel pumps in each tank.  I also 
had one-way valves on each line as it exited the tanks to keep the fuel pumps 
from simply pumping fuel from on tank to the other, rather than to the FI 
pump.  I then ran the two lines from the tanks to a three-way splitter that 
then ran to the FI pump in the trunk (the factory location on the later FI 
Jags.) Then the line ran to the engine.  The fuel return line ran from the 
engine back to the trunk via the old vapor line.  Then it split into two 
again and ran back to the tanks (again, via the old vapor lines,)  I had to 
have an electronic shut off valve in each of the lines to keep fuel from 
going into the wrong tank.  I ran the wires from one fuel pump in parallel 
with the shut off valve on the opposite tank so that when that pump was 
activated (via the original switch and wiring) the opposite tank would not 
receive any fuel.
And that was all there was to it!
