Default Need Help solving an Issue 08 F250 Super Duty 6.4

Ok I have an issue with this 08 F250 Super Duty 6.4
Power Steering with hydra boost
It came back after lots of work done replaced the WP, Drive belts and tensioners idlers and Fan Clutch along with the power steering pump was doing just fine a week later it blew one line all original never replaced and the reservoir leaked slightly around the seam so when the line blew he kept fluid in it all the way over to drop it off...

I figured out which line was blown and it has several pressure lines and several return lines being Hydro booster... so, being all are old and needed replacing I replaced all the lines and the reservoir and it screams and hollers I think it has air in the system but I can't seem to get it worked out...

Two questions Are it possible it just has that much air in the system from all the change out of the new hoses and such... If so are there any ideal of how to work/bleed this Air out.???

Or could it of not flushed out good enough and also picked up some of the crap out of the reservoir is it has a built in filter and may have caused the new pump to crap out. I can't see it being a bad pump within a week but I guess it is possible...

I went through the normal steps the first time by turning the wheels back and forth a few times till fluid level dropped some added more fluid and did it a few more times and then fired it up and all was working well during the first install of the new PSP.

And now again with the same procedure after replacing the new lines and reservoir and then fired it up and now it all hollers and screams like it has no fluid or low on fluid but it is full and you can see fluid returning back to the reservoir...

What am I overlooking with this... It's got me a lil bit stressed so I had to quit for the night to rest and try to get my head straight, but could use some ideas of what I could be or am missing here with this...

If fords are anything like a normal steering box, when you turn to the lock it bumps open a port and dumps the pressure to the reservoir. Hold it into lock for 30 seconds, crank it to the lock position on the other direction and hold it again. This should flush the air from the box. The power brakes should poop out the air if held down hard.
You have oil returning but there is an airlock that is trapping it in a hose or in the box itself.
There will be a pile of foam, and your reservoir will drop as oil replaces air. The danger is dropping it too low and sucking in air again. You may have to repeat this maneuver.
I have had so much foam in one I did last fall, I have had to walk away and come back next morning after it settled down.

Tried it a few times on and off through the day and still doing the same thing I have a feeling something went south of the arctic pole with the power steering pump or Hydra-booster

Ford had an adapter to put on the reservoir in place of the cap, and put the system under a vacuum and turn the wheel lock to lock, on most newer ford vehicles that was the only way to get the air out of the system. You could probably find an old cap and fab something up

Thank you... I can do that, I still have a cap for it I can modify... I'd have to use my vacuum pump for vacuuming AC to pull a vacuum or should I use the mity-vac hand pump???
If nothing else I'll replace the Power steering pump again and start fresh...
if this other does not work...

on a gas engine I would use a vacuum port on the manifold but a diesel I would use the ac vacuum pump but keep the fluid level low enough so the fluid does not get sucked into the pump. It will sound really loud as you turn the wheel back and forth. If you take the cap off you will see a lot of foam. May have to do it a few times than shut it off and let the foam go away. Never had to replace a pump after just replacing lines.

Sounds like the right path to me. It's one of the reasons I despise Fords. They make F--n-A-Sure every garden variety repair requires one Special Tool Two examples come to mind right off the top of my head. 90's Escort timing belt R&R the entire job can be done with metric wrenches from HF except. Wait for it the Timing Belt Tensioner takes a little dog leg 10mm wrench. Intake plenum on a 90's 5.7? (351) every bolt is run of the mill standard metric except for one in the center of the base of the plenum that requires an extra long male torx driver to remove. Sorry, this shit is not a coincidence. It's pretty pathetic when I can wrench all day on Japanese Nissans (when they actually require repairs) and after 10-15 years I think I might own 3 special tools mostly because they make it easier not because the job can't be done without them.

I prolly have 6-7K in specialty tools for HE, FE, and automotive work for all sorts of shit some I haven't used in years vehicle specific crap and I am still buying as needed kind of like machining tooling it never stops...

I messed with it tonight got it to act right but something is causing it to create air in the fluid I have a feeling the new pump as I discovered was new from A1C which was bought from ford... it's, in my opinion, a POS so I'm going to bite the bullet and buy a new one from summit racing and see how it works out almost and I mean "almost" betting it's the problem... parts from A1C are turds at best...

Well here is the outcome... The system developed a leak in one of the return lines! And upon the leak, he drove it approx 280 miles putting fluid here and there to get it back here... The system if fluid specific so now we have a damage new PSP and lots of blown seals in the High-pressure lines at the connections form apparently cavitating at high temperatures

So now come Wednesday I will replace all and be 100% sure I ordered me a vacuum adapter kit for specifically vacuuming power steering systems...
Fing crazy what they want for a good adapter set for this but I do enough of PSP replacement it warrants buying the kit.

They make a cheap stopper set but I think he better cap and plug kit will be maybe longer lasting but I'm trying to decide just who to order it from. as price varies from dealer to dealer 65-95 but all almost look identical in the kits...

I believe they are all rebrands of the same including the OEM brand and I think OTC might be as well.

Anyway, I am dreading this because it is a nightmare to get to all the crap and I'll be repeating all the same labor as when I replaced all the belts and tensioners and etc. tons of shit to pull of just to get to any of it including pulling the fender well and skirt...

OH HOW I HATE Working on F'ing Fords But life is too darn short to whine about a little spilled milk ay... But with my torn muscle I'll be doing plenty of whining and wailing I'm sure... have been trying to do as little as possible with it and have prolly overdone it, trying to do as little as I can..

I have however had a bit of help lately "my Son" but keeping his attention toward what I am paying him for is worse than pulling wisdom teeth...

But I should credit him, He has at least tried to help me and has done more of the strenuous stuff Or parts that are a bit challenging for me to do at the moment...
