Lift pump/pusher pump ?

See my sig. With my stock LP I was able to pull my FP down to 0 at will so I added a Holley Blue back by the tank. With the Blue my fuel pressure is around 20 psi @ idle and 15psi at WOT. I have heard that the combo that I am running still isn't enough fuel to keep the CP3 happy. How can that be if there is still positive fuel pressure at the CP3 inlet? wouldn't the fuel pressure still go to 0 if the stock LP was the restriction in the system? I eventually want to put a FASS on it but am trying to take care of some other stuff 1st if it won't hurt my truck like it is. I need some opinions please

It depends on where you are getting your reading from... if it is being taken at the CP3, then you are fine... but if you are getting it somewhere else, you could be seeing pressure as a result of a restriction in the lines and actually drawing the pressure to 0 at the CP3.

Thanks for the advice, I am getting the pressure right @ the CP3 inlet
