Fuel Pumps

So I've been reading threads about mechanical and electric pumps. It seems to be about a 50/50 split between the two of them. However I plan on keeping my car carbed and dont really want to spend the extra cash on all the added parts needed to install a electric pump.

Currently I run a carter stock mechanical pump, but I want to run braided line instead of the hard line that is there now. I would keep the stock sending unit in my tank and found a 5/16" flare (compression) to AN fitting that would work on the tank end.

Has anyone else done something similar to this same set up? Using the stock sending unit and leaving it right away with braided hose to the fuel pump?

I was also curious if you have to use a regulator if I installed a rebuildable mechanical such as the edelbrock like pictured?
