7.3 99' HPOP replacement, tips?

[golfer]

Could be an upgrade maybe. It don't have to be broke to replace it.

..just assumed the "buddy short on money" deal meant he was trying a repair...but maybe short on money was just referring to the labor...no idea.

Sorry for not keeping up, I had a family emergency to tend to these last few days. Thanks for your suggestions.

Can't I use two flat heads for the quick connects?

As for why it is being replaced, IPR was changed out 20,000 miles ago and there are no HPOil leaks (or so I am told) and that it is only making 20psi of HPOil. I will check to see if IPR DC% rises slowly or spikes up to 65% with AE, not sure if the 7.3's IPR reacts the same way the 6.0 does.. i will be starting this tomorrow morning, thanks for the help

EDIT:

I gave him my cost on the part and am doing the labor for free. He needs his truck running, uses his truck for work and has two young kids.

Got the HPOP in, IPR DC 65% ad not making more than 200 psi. Cranked for 6 times no more than 30 seconds with 5 minute intervals.

We replace the IPR as well. Won't go over 280psi when cranking.

Any ideas? We found shavings that were aluminum when we yanked the pump and IPR

Look on the bright side, you only have eight things left to check

Only thing I can think of is injector O rings causing the HP oil leak. But thats an educated guess..Pulling injectors Monday.

Those are the eight things that i am refering to. If you had metal shavings in the hpo then you prolly have some hung/damaged injectors too.

:doh: i yanked the valve covers yesterday and didn't see any excessive oil coming out of any of the injectors. I did see that there was more oil laying around cylinder 7, then any other area, not sure if that's normal. Thanks for the reply!

 

[MorganY]

Picked up a set of o rings for the injectors. Fingers crossed.

Well, seeing as how this is the SuperDuty section, and the title of the thread is '99 HPOP replacement, I would be willing to bet he has Quick connects.

BTW, I took mine off with a big screwdriver.

I wish mine had been this easy, I tried EVERYTHING, including the tool from Ford. Finally just unscrewed the the connects and took them about 5 places (Including Ford) with no luck. Everyone thought I was retarded until they tried. FINALLY, one guy popped them right off with a tool from a grinder set. My new lines pop easily, thank God.

dare it be asked whyyyy the hpop is being replaced?

from where I sit...the pump either starts the truck or it doesn't...and 99.9% of the time..the pump isn't the problem on a no start..much much more likely to be a faulty IPR or inj o-ring or inj issue if the truck isn't making enough HPOil to fire...

This is kind of what I was wondering.



You know Morgan, I certainly could have helped with this issue. I have PLENTY of (against my will)HPOP and the related experience.

I remember that episode.

Sorry I didn't have your number, I'm out in magnolia. I sucked 40 cc's of fuel/oil out of 7&8, 10ish out of the rest, and the motor won't turn over when I tapped the starter. Pulling everything back out and turning the motor by hand.

Have fun with that.

Did you spin it over with the glow plugs out? You can only vac out so much. You can still have enough in there to cause issues unless you spin it with the GP's out.

I am in the process of doing it now. I vacuumed as much as I could, inside and outside of the bowls as best I could, now the glow plugs are out and I'm cranking it with the starter to clear out the rest.

Did you reinstall the injectors first? If you are leaving the the injectors out while "clearing" you are just allowing more into the mix?

Yes sir, injectors are in.
