Hi Jim,

Todd's system is a "quasi" = returnless=20 system. The fuel is returned to
the input of the fuel pump = instead=20 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=20 Todd's diagram and description go to:

http://www.rotarywiki.com/ and = search=20 for "returnless".
