That is basicly what slatter's system does.
My only concern is, i dont know if the fuel pump is strong enough to pull the fuel through the block.
Also, the fuel lines are much smaller ID than the coolant lines, you would have to design your block, which is restrictive as it is, with even smaller ID barbs. That introduces much more head.
Plus, the tank is, at most, arround 15 gallons. A good pump with not much restricttion can pass through 15 gallons fairly quikly. After the initial pass through, the entire tank is as cold (actually colder) as the fuel would have been if you were cooling it inline. At this point, any aditional cooling will make it even colder than it would otherwise have been.
SlatterSpeed, is there a point where its too cold? Like is it possible to cool it too much? I'm nottalking about cooling it to the point of freezing, but is there a certain temp, where, if it passes that point, your doing harm to horsepower instead of good?
