I suspect that a lot depends on the level of fuel in the tank and various other factors which might sometimes cause siphoning to begin on its own (which is one reason for the golf-tee trick). If you were able to clear the lines of air and start the car easily with the normal hand pump after completing the filter change, I doubt that there's any problem. If you had trouble then, though, there may be a blockage at the tank screen, or a fuel line beginning to deteriorate inside.
