Fuel pump swap for HO question

I know it's been gone over a time or two, but I can't find anything on it.
Any of you that's went from a 3.8 to an HO have to change to a higher capacity fuel pump?
I was wondering if I'll need to put in a new pump while the tank is down when I get the fuel lines for it.

Fwiw, the engine will be a stock HO, (converted SO block) with no mods.
I kinda recall someone reporting that their car didn't run as good as it should've until he went with a higher flow pump..was this 1WldBrd?

I would, as even the stock HO pump is under fueled.
