They finally blew.
Was replacing the driver side wheel bearing/hub tonight and got in the cab to turn the knuckle as to better get my socket on the nuts within, and when I went back under the truck I noticed fluid everywhere...
Yep, you guessed it - power steering lines went (ironically under no load). Thankfully we had the two in stock at work so I was able to get them repaired at the same time - I just happen to have gotten home from being at the shop for the past eight hours.
I will say though, as much as this truck makes me want to smack it with a sledge somedays, it is at least nice enough to break when I'm either at a shop or I am already working on it for something else.
Also, about how long does it usually take for the pump to purge the remaining air out, a week or two? Just curious what to expect.

You should get most of the air out when you get done with the hubs. While it's up in the air, start it up and turn the wheel from stop to stop a few times making sure the pump is full of fluid. That should be enough.
Oh, and be sure to pump the brakes a few times too. Make sure the air is out of the hydro-boost system too.

You had two lines go at the same time?
I just received the high pressure line from RiffRaff. You have me thinking now that I should have gotten the low pressure one as well...

Thanks John, I turned for about five minutes while on the jack stands, but it still seemed to be whining a little more than usual so I think I may just have a bubble trapped somewhere slowly making its way out.
To be fair, I wasn't 100% sure which high pressure line went out - be it the pump to hydroboost or hydroboost to hear - as both were covered in fluid. I went ahead and replaced both though as at 370k, if one went with no load the other was soon to follow.
I think the one line had been repaired at some point in time due to there being a crimped connector in the middle of the hose.

Are you sure the lines blew? When you turn the steering with the engine off, its not uncommon for a geyser of power steering fluid to shoot out of the top of the pump. It can/will over-power the puny little plastic "ramps" holding the cap closed. It makes a huge mess everywhere. I hate it when the mechanics do it when doing an alignment, depsite the fact that I tell them to start the engine, so as to avoid that. of course, I'm not a "professional", so they feel free to ignore me.

I had the one from the hydroboost to the steering box blow on my parts truck and all i had to do was run the engine to find it. It killed me to buy a part for this thing but I do need to move it around yet and I got the $32.00 one to get me by. As you can guess it is nowhere near the quality of the OEM, which I would recommend for a truck to be used. I did not use any VIN to obtain that hose, just identify where it went.

Correct, they weren't quite as robust feeling as the OE ones, but they are what I had at my disposal and I needed the truck out of the bay - adjusting valves in a cabover tomorrow after work. Hopefully they'll last a good while.

So I just got done doing my hubs. Last night when I manually turned the wheels it did just what carguy3j said. It blew the lid off the res and fluid everywhere!

I'm fairly positive that the line itself actually blew for me, as when I looked at the line again the other night, only the underside of one was wet and the quick-fix looking crimp on the other had fluid centralized on the downhill side of it.
