Analysis

The pilot had made a precautionary landing due to enroute weather. After conditions had improved he obtained a weather briefing for his intended destination. He was told that there were tstms in the area but that conditions were VFR. After departure from the enroute stop, the pilot attempted to transfer fuel from an aux tank. He turned the pump on but did not open the transfer valve. When he arrived over his destination, there was heavy rain over the airport. He elected to divert to an alternate. On the way to the alternate, the engine lost power from fuel starvation and a forced landing was made in lake lanier. There were 20 gallons of fuel in the aux tank at the time of the accident.
