Having fueling issues please help

[cumminsbus]

SO I am having some issues with my truck fueling. Stock cp3 and everything in my sig. Rail pressure is only 18k going down the track. I know that is part of my problem. Here it the pass my truck was fueling the worst on. I threw a CEL of rail pressure sensor on this pass.

You may have a leaky relief valve in the rail. Just a guess.

Well ht3500 put them in over a year ago so he can verify the size of em. I think I like the tire and wheel combo also. I tried to see if the tailgate trick did anything but it didnt. :bang

Go with a modified CP3, at least a stage 2. That will solve your problem.
