im not 100% sure about the injectors, but i would guess you wouldnt need to change the fuel pump.

And you do NOT need to use a fse valve

As jdfiesta said, use the standard fuel rail and regulator, as Ford very nicely made the regulator adjustable

Because they believe all the advertising and hype you see in the adverts in certain car mags.
Yes, certain types of cars might need them to raise fuel pressure, but you DONT need it.
