Can someone confirm if I need to drill the regulator in the stock basket assembly with the Aero 340 or not?

Thanks in advance

The speculation through my fuel pump fiasco is that I probably needed to drill the regulator since I took the black venturi piece out completely and it still did not lower my fuel pressure very much. Since I decided to leave it the way it was and since it probably is not the source of my wobbly idle I ended up putting everything back the way it was... unfortunately all I can offer is speculation =)
