Lantirn,
Let's assume you are just above stall speed. Even at that speed there is no way that a fuel leak (assuming your leak is external to the engine) is going to make it's way forward against said airspeed airflow and be ingested by the engine. The fuel will be blown aft and atomised by the airflow and by the time you have completed a full holding pattern 360 the atomised fuel will have descended and evaporated.
With an undercowl fuel leak I doubt very much that even with undercowl airloads forcing the fuel forward it will not be ingested by the engine due to the inlet cowl to engine core bulkhead preventing it.
