I can't understand that either, drives me nuts though. I keep checking the level just to make sure I'm not losing any. Let us know if you come up with a solution.

The Ford C2 pump is sooooo well known for whining from the factory!
Air forms in the pumps, causing them to whine. Doens't at all mean their bad, air just forms in them, why? God knows....
The one in my 89 F150 was super loud to the point it was embarasing driving it. The truck had sat in a barn for 2-3 years before I bought it. I checked all fluids before driving it home where I parked it for 2 months while I was doing work on it.
After being on the road for about 3 months, the noise completely went away. it got less and less noticable till it finally got quiet. I guess the air bleeded out. Level was toped up at first, but as the noise reduces, the level went down, so I kepted adding untill the noise was all gone, and the level quit going down.
It still does whine very loudly just parked when you start it up in really really cold weather. It quiets down onces warmed up though.
A popular P/S pump swap is for the Saginaw pumps found only in Ford vans, E-series.
All E-series vans had Saginaw pumps, they are very quiet and can't even feel your self turning the wheel.
The steering wheel in my 11,000 pound motorhome is easier to turn than in my F150.

Maybe this is what I have. What identifies the Saginaw pump?
My F250 pump is silent, with zero resistance on the wheel (to the point of having to be careful if I take my eyes off the road), but the 88 F150 I just sold was heavier to steer & it buzzed & whined continuously.
Regarding the original post, I have read of using a hand vacuum pump to remove air pockets in the system & remedy the whining - by applying vacuum to the reservoir while turning lock to lock a few times with the engine idling.

Don't turn the wheel hard over and hold it there. Go to where it stops then back off a bit.
Holding it at full stop is very bad for the pump and steering components and will cause premature wear and possible leaks.

The saginaw pumps have a GM looking cap. The tank is metal.
Any Ford Econoline van pre-1991, I don't know if the 92+ vans still used it, but I am sure the old vans used it.
You'll just have to find a Ford van with the same engine as yours so everything can swap over.
Heres what a Saginaw pump looks like exactly.

Just because these trucks like to keep you guessing, my 88 150 plow truck sits most of the summer. I move it around occasionally to haul some brush or something but not really all that much. Last summer the pump started getting louder than normal. However, now that it snows several times a week and it is getting used regularly, it has quieted down. I thought it was going to get worse especially on cold start ups but it has been fine!?! I'll take it!
