DThe first application of returnless GM efi which I saw was the port fuel
injected big block engines.  I believe many manufacturers are using
returnless systems now that OBD II evaporative emissions standards are
in effect.  Returnless systems do not transfer heat to the fuel tank.

I>Was looking at the price of LS1 crate motors today (serious value in the
DI>BHP/$/pound stakes) and noticed a comment about having returnless fuel
DI>rails. Is this a stock Gen 3 feature and if so does anyone know where i can
DI>find out how they did it?
