Fuel pump questions
Good morning,
I am nearly done swapping an ls3 into my 02 SS and unfortunately i have discovered that i need to change my fuel pump (its been sitting awhile).
It is a factory pump and i have about 105k miles on it so it wouldn't hurt to go ahead and replace it.
So my question is, with the engine i have built which is a cam only ls3, using stock ls3 injectors would a factory replacement fuel pump be enough to feed this engine? Or do i need to spring for a higher output pump?
Im not sure how much power i am ultimately going to produce but the cam i have installed from EPS is slightly larger than the cam that GM uses in their LS376/525 crate engine so i am anticipating making a bit more power than what that engine produces at the flywheel.
Thanks guys, i am totally a fueling newb here so i am humbly asking the fueling gurus for help.
Thanks!

If your replacing the pump, you might as well splurge now and do a racetronix fuel pump and hot wire kit. I did so with my Heads and Cam swap for the peace of mind and I am happy with my decision. The stock fuel pump is around $100 bucks anyways. Whats an extra 200 for an upgrade when your already paid for a new engine.
