For what it's worth, on any 2003 6.0L that has darkened my doorstep with insufficient ICP, it's pretty much always been the high pressure oil pump itself that has been the culprit component that failed. 2003 model years are a ROYAL pain in the A** to air test. You would need to remove the easiest to access valve cover (which is probably the driver's side) and air test it through the port on the top of the straight oil rail. If you choose to disassemble it as far as removing the high pressure oil pump, you can also insert a rubber tipped air nozzle directly into the branch tube. By doing it this way, you eliminate the high pressure oil pump, discharge tube and IPR valve out of the equation. If applying air into the branch tube directly fails to reveal any air leaks, you'll know it's the high pressure oil pump that has failed, which you've already removed. If you do hear any air leaks, you'll know if you're going LEFT or RIGHT.
