Well, I replaced this part today, and it was pretty painless. Took me about forty minutes, and I work very slowly. Annoying that the dealership was saying it's a 1.5h labour charge. I know that's all based on a "book charge" and they can't change it, still, seems impossible.
What's interesting is that the fuse was blown, so that pump wasn't doing anything. It must not really be needed once the engine is warm, because I didn't think the brakes felt bad, other than for the first thirty seconds after startup.
For anyone considering doing this themselves, I say go for it, very easy using the instructions in that fordtechmakuloco youtube video.
I paid $255 for the Pump, and $10 for the fuse.

Add me to the list of failing vacuum pumps. Making A LOT of noise now, although I still have brakes. Starts it's chirping right at start up, and doesn't stop until rpms come up. I paid 350 on Amazon for the pump, not due to arrive until Wednesday.
In other news, NHTSA is looking into this issue now.

I just actually replaced another one of these pumps last week. It appears the replacement pumps have been updated. In the first photo up top, I have the two pumps side by side. It's pretty obvious what the difference is between the two. In the second photo of the replacement pump up close, you can see the diaphragm portion of the pump is now made of plastic, which doesn't corrode the way aluminum will when exposed to the elements, as you can clearly see in the third photo, causing its eventual failure.

Just got my truck back for vacuum pump replacement. Spent 10 days in the shop because the installation kit was not ordered. Happy to have my truck back.
Two questions though for those who have already received new ones: does the new pump seem much louder? and does your new pump seem to always run? Spoke to the service writer who took excellent care of me and said all is normal, but until the problem with the old pump I never new it ran. Just seems odd. Thanks.

Let me check my paper work when I get home. Knowing about the national back order I checked first to make sure they had a pump in stock. They said they did but then told me at day 7 they needed the install kit. I had quite a laundry list of things for them to take care of which is why I think they had my truck so long.

Hey Seventyseven250, Just checked my paper work and here is what I found: part number for vacuum pump assembly(bl3z*2a451*a), fuse(6e5z*14526*ca), and also a 9c490(no description). Invoice states that they replaced vacuum pump and harness. Hope this helps. Who knows, maybe they did not have the pump and were just feeding me some BS.

I would like to let you know that it is now covered until 240,000 kms or 10 years

Yep. My truck has been in the shop for 3 weeks.
You would think that with an issue this common, they would have a few in stock. The part still has not come in! 😡
