Fuel pressure ?

I've been slowly noticing that my fuel pressure will drop. At first only at WOT and lost 10-15#'s. My FICM programmer came in yesterday and I loaded the 40 tune and drove. Truck drives great and throttle response is awsome--but at WOT it falls on its face--looked up at the gauge and it was at 20#'s So I stopped at NAPA and got one of their pumps, installed it and the same thing. I have a RR from Dozers Diesel--Still uses the stock front lines and filter bowl--caps off the return port and new lines from the rear of the heads to the reg. and back to stock return line. i changed the upper filter as well. Maybe something in the tank restricting it from sucking fuel?? Without the FICM tune it still dips down past 30. Stock injectors---I have had problems with stiction on number 7, but a fresh oil change with T-6 and a bottle of archoil and it has been fine the last couple days. Any thoughts?

Have you installed the blue spring update?

Edit: I wasnt paying attention, you have an RR.
Your suction foot, could have failed. How much fuel in your tank when this happens?

Blue spring is an oem updated fuel pressure regulator spring that prevents fuel pressure from dropping below 45 psi. It installs in the fpr located on the side of the secondary fuel filter housing.

since the return port on the filter is capped off, the blue spring won't help, in fact I think all the factory regulator guts should be removed with this configuration...

Not sure what you mean by this? You should do that and let us all know how that works for you?

He has a RR kit with an external regulator, the one in the filter unit is not being used thats why the return on the filter unit is capped off. it will cause restriction and it's not needed.
