I never change the fuel injectors yet because my A/F gauge did not indicate I needed to. i suspect they are under pretty high duty cycle. I do not see an auxiliary fuel pressure regulator in your photo. You need one of those. I can send you my install instructions when I bought mine new if you want. Mine was a prototype for Sebring before they sold it to Jackson--so its pretty old--but has over 100K on it.
