toyota years ago went to dead head fuel systems in their vehicles.
they believe that fuel returning to the tank is heated and heats all the fuel, then changinging the emissions and character of the fuel, bringing down the power of the engine, and increasing emissions. they use a stepper style pump, based on throttle valve openning and load on engine to adjust fuel pressure needed.
I personally like the idea of a cool can on the return side cooling the fuel in the tank thus cooling the fuel being delivered.
I've also heard of dry ice in the tank, thanks ed o'brien for reminding me. but don't know how it affects the fuel, doesn't it smoke out then, thats my question. sure would cool it nice tho.
