I need to know if installing a higher flow fuel pump will make my car run rich or richer than stock?

I am only installing the pump no injectors or fuel rail.

i should be getting my new pump today, but a new pump will give you more flow when gas is being pulled out. usually the fatremarket pumps biggest selling point is running cooler.

injector size determines if there is more gas dumped into the engine. so if you have bigger injectors, it helps to have a bigger pump
