Larry Shepherd’ Mopar Small Block Engines book says keep mech fuel pump when adding electric.

This is a 2016 book. He is talking a performance street engine. He says use a regulator if the mechanical pump is removed. Page 124-125 of How to build Max Performance. I’m having to put in a new fuel tank and want to use a tank mounted pump while I’m at it. The reason is that I’m doing conventional carbed small block for now but want all future options open all the way to a modern hemi 392. I don’t want to mount a regulator near the carb and spoil the stock appearance. I’m thinking I could simply connect the return at the mechanical pump. Another option I’m thinking about is a regulator near the tank.
