First off why did you change the rad and pump? Now it appears that coolant is being pushed out of the o/f tank. Could it be combustion gasses doing this? To find out get yourself a detector kit that will tell you if the coolant in you o/f tank is mixed with combustion gasses. If it is, well you may have a H/G problem.
