Hi,
        I know that this has been discussed before but I still have not found a good solution. The Limo EZ (same as Long EZ) has two tanks mid wing design.  Original design requires fuel from both tanks to be fed to a valve and then back to the engine.  Problem, fuel injection requires special valve to return fuel to tank it was delivered from.   This means 3 more lines in addition to the 3 lines already in the cockpit.  I think this is getting complicated.  I like the sump idea creating one tank but the problem is return.  If you return it to the sump you heat the fuel in the sump up.  Is there any way to divide the fuel return so it can be returned to both tanks?  If you tee the return lines does the fuel divide evenly?  I thought about another sump to return the fuel to and let it drain into both tanks.  Make it higher than the delivery sump. I am trying to avoid a transfer pump but it would need two lines instead of 3 and they could be placed outside the cockpit.  What about using two pumps that can be synchronized?  One could pump fuel from the right tank to the fuel rail and the other could transfer fuel from the left tank to the right tank depending on the fuel flow being pumped from the right tank?  Return fuel would go the the left tank making a continuous loop allowing the fuel to cool? I keep thinking of my friends Bellanca with 5 fuel tanks a fuel management nightmare.  Thanks for any help.
