How do you know the pump is bad? Have you checked the system?

As for the video's go to you tube and run a search on hpop removal there are a number of good ones. Also look at the testing video's wanna be shure it is an hpop problem, not a job ya wanna do on the maybe. $$$$$$$ and a bunch of work.

I haqd a ford diesel mechanic check it out and he said that the oil pump was only putting out 130 psi. He said the pump had to be replace.

what pump is the best pump to replace the factory one with ? also if I use a genuine ford pump do i need to or should i upgrade the hpop fitting as well? Not sure about the difference between the aluminum pump or cast pump ? I want the best pump I can buy.

With it being an 04, it doesn't have the STC fitting. I'm curious how he determined the pump was bad.

he told me he checked the pressure. it was reading 130 and he said its supposed to be 500 psi and above. Im not sure how he checked the pressure. My motor is an 03. it says it on a sticker on valve cover

The ICP pressure has to be 500 or more for it to start. If he's just watching the ICP and it's showing 130 psi, it won't start but that doesn't mean the pump is bad. Only way to know for sure is to command the IPR valve close and apply a minimum of 100 psi of air to the system through the ICP port and listen for leaks.
