I've never heard of "overworking" a 255lph pump on that type of setup. You have a return on your fuel system, so your pump does its thing, and whatever fuel isn't used goes right back in.

I have a 255 right now, I'm not going to be boosted for a few weeks, and it's working fine for me.

Someobody correct me if I'm wrong, but I don't think you'll have a problem with any of them.

Out of those two, the 190lph, 255lph is overkill.
Interested in knowing what a stock d series fuel pump can handle though.

I am running the stock d fuel pump and injectors at the moment at 6psi.
No fuel starvation, but I bet I am pushing the limit.
