The NTSB's narrative final · quoted from the NTSB record

While taxiing to the runway for departure, the pilot noticed flames entering the cockpit below his feet. He immediately stopped the airplane and shut the engine down and he and his passenger exited the airplane. The airport’s Aircraft Rescue Fire Fighting (ARFF) team responded and extinguished the fire, which was originating from the engine compartment. A few minutes later, the fire reportedly ignited a second time and was immediately extinguished by ARFF personnel. Examination of the airplane revealed that the engine firewall was fire damaged and buckled. A "B" nut attaching the firewall end of the fuel line from the firewall to the engine driven fuel pump was found "finger tight." When the airplane was placed in a tail high attitude, fuel was observed leaking from this fitting. The reason for the loose "B" nut was undetermined.
