Best place to have any breakdown is less than $200 tow from the driveway.
Out on the road would of really been sucky.
I recall that there is something about using razor blade to cut the connections so you don't pull the other seal out of it's track.
AAA free tow. I was about 1 mile from home lol
Once I broke the bond it came up. Ordered a new seal just for measure. Hoping to have the pump here Thursday and the truck running again Friday. We have a trip next week of about 450 miles each way to I need to get some more miles on this thing. Engine wise it sounds good and feels good.
Wasn't that for clearing the "J" tube from rubbing on the top of the cover?
I think some had done a little die-grinder mod to clear that space.
But don't take my word on that one as I have a 2006 and don't have to deal with that.
Blown STC Yes and that has new parts for the fix and was fixed before I took it all down.

Have all three in my possession. The tallest one, where you can tell from the exterior, was for the '04.5 with the taller HPOP. The one on my truck showed no evidence of rubbing. I can only conclude there was some out of spec bends in the tube or cover that resulted in some engines having an interference issue. When I was looking at eBay covers, a good source for pictures, I never saw one with rub marks. I think it's rare.
The common failures of the early HPOP that I have read about:
Housing weakness (back plate wear-out)
Swash plate issues (a light press fit is intended to hold the swash plate in place but apparently they can spin and cause failure).
Rotating cylinder cracking.

I think CNC fab cures these issues. I hope! Should have my pump in the next day or two.

Wasn't the issue with rotating also the cause if the spit out BB?
That was the speculation. But that is part of the inlet port. So any back pressure would not only be at the back of the ball, but also through the HPOP screen and into the reservoir under the oil cooler, and beyond. I think is was just a bad design of it being a press fit. My HPOP was also staked at the port, making it a tighter fit.

what’s weird is super duty service had a video where he showed two remanned motorcraft pumps. One had the BB and the other had been tapped for a plug.what’s the purpose of the port? To alleviate trapped air?
Some of the aftermarket companies go for a tapped plug to insure it stays blocked. Others have staked them, as mine is. I think it may just be to close where a drill had made a port in the casting.
Hartwig is doing what I wanted to do, take an '03 apart. But in the two years I've been looking at eBay and Facebook for a cheap one, they all have been more money than I want to invest.
There are actually different castings/configurations. I had a short discussion with someone who knows them and one day planned to get back to him. Some of the images I've grabbed.
Likely from machining operations I would think.
But I am 100% guessing as I have never had one of the round pumps to look at.
From what I recall about the guy that did some home brew machining on the pump and placed three pins into the
top end of the pump to keep it from rotating in the housing he thought that when the housing spun it allowed high
pressure to the back side of the BB.
Dang now you have me curious and I will have to find that document that was posted about the work he did. When I find I will post it.
