You should check the fuel pump pressure. A simple vacuum gauge/fuel pressure gauge available at almost any auto store will have one. The pressure should be about 4-5 p.s.i. but not more than 6 if I recall correctly. If the fuel pump does not have a pressure regulator then perhaps it is pushing fuel at too high a pressure and as already mentioned it is getting past a faulty needle and seat.
