What fuel pump are you guys using for FITECH?

I just bought a fitech unit and fuel command center off my buddy yesterday, never opened it but I’d rather just run an electric fuel pump. I want an in-line pump so I don’t have to remove the fuel tank. I think the throttle body has an integral fuel pressure regulator? So then what all would I need to just use an inline pump? I know fitech has an option for this, but It’s kinda expensive and I’d rather use a trusted brand name anyways. I was not entirely set on fitech in the first place, but I got a good deal so I figured I’d try it out.
