Hey, we missed you at Anna this year. It is more than likely coming from the shaft at the packing glad. Tighten up the 2 nuts on the studs that face the engine from the pump. But not too tight, you want an average of one drip per minute at idle to keep the shaft from getting hot and burning up the packing. They will be the first nuts you see around the pump shaft after the ujoints. This is just my guess because I had the same thing going on with mine, and after tightening them up the leak stopped.
