I believe you just got the year wrong on your 35 Evinrude made lots of pressurized fuel systems in the 50s. I would not recommend using an electric pump. I doubt that the carb would function correctly with that much fuel pressure. What was the problem with the original system. It did work very good.
Yes you could put some kind of fuel gauge in the tank if needed.
