The change is under consideration to prime the carb and avoid dethanol issues. What problems did you experience? What fuel pump did you use? What was the gph and psi rating? What lift capability did the pump provide on the inlet side? Where did you mount the pump? Did you include a filter on the inlet side? What micron rating was the filter? Was there lots of debris/rust in your fuel tank? Was it wired to engage for >3 seconds when the ignition switch was set to ON, and then stay on when set to START? Was it wired to shut off if either rpm or oil pressure drops out? These are all the things I am evaluating. Apparently, others have done this modification and really like it.
