Hi,
I converted a '76 Jag Xj6 to FI.  Dealing with the dual tanks was not easy.  
I ultimately converted them to a set up that was similar to the '80s FI XJ6s. 
 I was reluctant to do this initially because it seemed overly complex.  But, 
quite frankly, nothing else worked.  I could try to explain it, but you're 
better off looking at one in person or at a good diagram in a manual.
Instead of using the FI fuel tank from a later Jag, I just used the original 
intake pumps to supply the main FI pump in the trunk.  I used all the jag 
brackets and electronic valves from an FI  XJ6 that I found in a junkyard.  I 
would have used those tanks, too, but the Junk yard punched holes in the 
bottoms to drain the fuel out!
I just used the vapor returns lines as the fuel return lines.  I had to use 
electronic shut off valves to direct the fuel to the appropriate tank (like 
the factory did, so one tank doesn't overflow).
If you need any advice or clarification, feel free to email me.
Ted
