If you get a CB or Carter rotary fuel pump for carbs, it is self-regulated at 3 to 3.5 psi. So no regulator needed at all.
I've never been a fan of the Facet shake-rattle pumps.
But yes, no matter which electric pump you use, they like to push the fuel.
The manufacturers and just about everyone else recommend a pre-filter before the pump. I use an after pump filter as well, but that's optional.
