what do I need to do for my rail?

What do you mean by "all my problems for the rail"?

If you have low rail pressure because of a faulty rail relief valve, the Arson kit is not going to solve the problem. If your relief valve is good, then the Arson kit will deliver more fuel to the rail and should help with draining the rail prematurely.

You can check your relief valve by pulling the banjo bolt out of the valve, very gently bend the fuel line out of the way, and start your truck. Bring the rpm's up slowly to raise rail pressure to see if the relief valve is letting loose. Lay a rag over the valve first, mine blew fuel all over the underside of my hood, made a mess.

Hope that helps, Jess

Your stock cp3 *should* be able to handle "90hp" injectors....first things first, you need a rail pressure gauge.
