My truck keeps throwing the low fuel pressure and low rail pressure ligth when I'm on the interstate cruising and stays are 10-12k rail pressure even when I step on it then the pressure jumps back to normal pressure and it's hit or miss also sum time I can go on a 600 mile round trip and it doesn't miss a beat and there times it throws the code no stop and I just installed a fass 150 a week ago the has a 2nd gen swap and ATD efi on it with about 211k miles
