Fuel return question for fuel injected 66

I am ready to put a 5.0 fuel injected engine in my 66. I had already planned to add the return line to the fuel sender plate by brazing in a tube. I had seen this in another conversion article I found while researching the swap. I read a few days ago about someone on the forum that they added the return to the tank drain. Any advice on which one to go with, and any problems experienced?

Thanks
