2003 F350 with the 6.0. My high pressure oil pump went bad. What caused it?

Question

I've talked to many mechanics in the area and no one knows why it would happen. No one has even seen one go bad before. Not even the dealership. Its spendy to replace and no one sells used ones. Can it be rebuilt? Why would it go bad? The truck has a Volant intake, Magnaflow exhaust, and an Edge performance chip.

Your dealership that you are dealing with must not work on them much or have no idea what they are doing. The 03 and 04 rexroth pumps (high pressure pump) are very well known for going bad. If this is your first pump you are lucky. The pumps are junk and normally nothing contributes to there failure.

They just fail. About 12-14 customer pay hours hours labor depending on the shop. We replace from 3-5 a week.
