Agreed. I do not know of one of those pumps fixing a problem on later 6.0. I know of several being replaced but it did not fix the problem (I'm sure some have failed somewhere and from various causes) 03-04 Hell yes, they die routinely at 125K or thereabouts.
Someone needs to air test it with an IPR adapter air test rig and find the leak. The air needs to be applied for 20 minutes at shop air pressure to push oil out through the leak in order for the test to be effective. If you don't air it long enough you can think you have no leak. If you have the air test rig with a gauge and a shutoff valve you air it up and then close valve and check for loss/leakage that way.
