Hi Jim,

Todd's system is a "quasi" returnless system.  The fuel is returned to 
the input of the fuel pump instead of the tank.  Without the cooler, 
much of the same fuel would circulate thru the fuel rail again and agin 
picking up heat.  To see Todd's diagram and description go to:

http://www.rotarywiki.com/ and search for "returnless".
