Summit has some products. Search under fuel cooler. I've seen billet styles but can't remeber the manufacturer. Look for radiator manufacturers and trans coolers as well.

I agree with all that's said above. In general if you are using a mechanical pump make sure the fuel lines are not getting close to hot (exhaust) surfaces. This goes for return line applications too. An electric pump with regulator/return line is a real good way to prevent vapor lock or fuel boiling.
