Russ,
Thanks for your concern, maybe we can get together and talk old hot rods. The cards were stacked against me that day. As soon as I noticed the fire, I turned off everything from inside the car. Got out and thought I shut off the master switch. We still do not know what started the fire. After the fire was finally extinguished and things settled down, one of the track guys said that the fuel pump was still running. It didn't make sense as the master switch was turned off. After some investigation we found the contacts in the master welded together and unable to open the circuit. This was caused by the main battery lead having the insulation melted and shorted to ground. The power to the fuel pump is routed in the same harness to the back of the car. The fuel pump power lead then shorted/melted to the main power lead. This made it impossible to shut off the fuel pump without crawling under a burning car and physically unplugging the fuel pump. In the future I will run the power to the fuel pump in its own harness. Hopefully fellow racers who have run the wires together will see this post and isolate the two leads. If other members read this post and know of a way to get this information to the entire site, it could save someone from disaster.
