The only "cool cans" you talk about that I've seen were used by drag racers in the sub 11 second range to get a 10th of a second or two. As far as I know they don't give very high yeilds.

I have seen a lot of late model mustangs and Grand Nationals use ice on the intake before a run to get a denser air mix, they swear it works.

The 914 pump uses gas to cool it, if you take one apart (don't try it unless it is not usable as a core) you'll see the gas actually goes through the windings and brushes of the pump to cool it (75-76 pumps anyway). Newer cars have the pump INSIDE the tank for this reason. The pumps do warm up, but there is such a volume of gas going through it I doubt very much the gas gets hot enough to really hurt anything. Don't forget the pressure reg and return line... Most (some at least) of the gas pumped to the motor is released back to the tank. If you are using a Facet style pump I "think" they use a diaphrame type pump so maybe they heat up more. The big thing is to put the pump out of the engine compartment and into a stream of cool air.

Back to the point, yes a "cool can" will help, a little. However an air to fuel cooler probably won't make a difference, I don't think the fuel gets that warm. Just keep enough fuel in the tank so the pump gets cool fuel.
