My son and I had lots of trouble with his supercharged Studebaker vapor locking. The fuel pump is in front so the hot air from the radiator blows on it. We were have over heating issues as well and were driving a car we had just got together from Nevada to Texas. We had to make several attempts to pull the grade leaving Gold Field, NV. I found a hunk of fiberglass insulation and some wooden clothespins to hold it on around the fuel pump. As long as we kept the insulation wet all was well. So I bet a cool box would work. Later we put an electric pump on just to use when needed. A larger line with more volume might help.
Any pictures of the car? It sounds great. What kind if racing?
