HPOP pump question
When is a good time to consider replacing the HPOP pump (mileage wise) if I am planning on tearing into the engine for a BPD air oil cooler setup?
I have 84k miles on the original HPOP and if I am not mistaken, my 2004 (11/03 build) does not have the infamous failing STC fitting. Up to this point I have had zero issues
I plan on replacing the stand pipes and dummy plugs, replacing the screen on the IPR..... Cleaning it and calling it good.
Open to suggestions from you guys
Thank you
Joe

I will admit that my decisions are based on monetary issues and the fact that I can (or could) do all my own work. I'm not one to replace parts unless they fail.
I have/had a 10/03 build engine. Like yours, one of the first builds with the wave HPO rail and they really didn't have problematic stand pipes and dummy plugs like the later engines did. Although I did upgrade mine at 190K when I built my current motor, I never had a problem with the HPO system at all. I even went back with a low mileage 03 HPOP that came with the 03 motor that I rebuilt and saved the 04 HPOP with 190K as a spare.
To me, personally, what you're wanting to do is, in a way, 3 separate jobs but I understand wanting to get at the HPOP while you have the top of the engine off.
I'd replace the HPOP with a dieselsite HPOP at the minimum. I would not replace it with a reman pump OEM or otherwise.
If I was going to do the standpipes and dummy plugs I'd pull the rails and do the cup seals also. I would only disturb those IF you're having problems.

If I had a 2003 or 2004 truck and had to replace the HPOP, I'd go with Diesel site's pump. It over comes the factory flaws and even if you don't get the high volume option, you still have a better pump than the stock one.

Hi Tim and Toreader,
I personally do not want to add more work to my already lengthy chore of replacing the OEM cooler with the BPD items plus adding another 1k+ of cost to an engine that has given me zero issues with the HPOP system, but there is always the "I shoulda done it then!!!" factor
I was given the advice on another site which got me thinking, but here I ALWAYS get a no nonsense dependable and credible answer from you fellas. The pump is expensive and even more so if I go with the Diesel site model which I read addresses the internal failing components.
As far as the stand pipes and dummy plugs (never done a set) I figured preventative maintenance but of course that involves more work and valve cover removal for a part that may not need R&R'ing.
So I guess in a nutshell.....Given the dependability of the 11/03 build, if you guys were in my shoes and were ready to do the same type of job on an engine that has no issues......would you do anything other than pull the IPR, inspect and call it good?
Thank you for the guidance
Joe

I don't think there's a simple answer to that question unless you have a crystal ball. I've always thought like Tordeaor_Diesel said above "if it ain't broke don't fix it" but that philosophy has led met change 5 glow plugs one at a time over the last few years. I know that's a "set" of something but I've always recommended changing just the bad one, at this point i think I'll recommend changing at least one side at a time, so I'd have to admit there may be a few exceptions to that rule.
I think your current HPOP has proven to be a good one and I'd be inclined to keep rolling with it. There are other considerations though, if you turn your own wrenches you could swap it on a Saturday with no problem but if you spend a lot of time away from home and it craps out on the road, it's not something I'd want to change in a hotel parking lot. Add to that the headache of finding someone to work on it who doesn't insist it needs new headgaskets also can be an issue. I also agree with TD (again) that an aftermarket unit is the way to go. Too many rebuilds (even from Ford) are bad right out of the box.

That sounds good......does that go for the dummy plugs and stand pipes as well....just roll with 'em?
Thank you very much

Sound advice!
I do all my own work and ofcourse I wish I had a crystal ball, I'd win the lottery and buy you all new trucks
but it is a crapshoot.I didn't want to be that guy in a month coincidentally posting a "no start" issue" thread and having it be related to the HPOP or dummy plugs/stand pipes
Thank you
Joe
