Did all of the ones on the lot sound they were about to self-destruct? My 2012 EB with 7000km on it (5 months old) started making this noise yesterday. I had never heard it before. It was quite loud, and I was able to record the noise on my phone for the service people at Ford. It happened 4-5 times at the beginning of my ride to work, for about 10-20 seconds per time.
They tell me it's nothing to worry about and that it's just the normal sound a mechanical vacuum pump makes, but I wonder how I went 7000km on it without ever hearing it before. No weather changes or anything to speak of, I had the radio at the same volume as always, yet I heard it over the radio and moreover, I could feel it in the form of vibrations through my foot on the brake pedal.
To me, it sounds like there would be a low noise as the pump works, but for the sound to be that extreme all of a sudden sounds to me like something's wrong with pump itself.

The new pump is about as loud as the ones in the other trucks I looked at.
However when the pump kicks on, it stays on for about 30-40sec,
If I'm idling along with my foot the brake pedal, the pump will pretty much stay on until I release the pedal.
I'm wondering there is a leak in one of the vacuum lines somewhere...
I agree, something is not right with your pump.
Since that noise hasn't been reported much on here, I'm guessing a properly working pump is
1. very quiet, 2. comes on for <10 sec.
Since 'noise' is subjective, the dealer can always say it's 'normal'. Have them compare yours with a '11/'12 on the lot.
No wonder they replaced that electric pump with a cam driven pump on the '13's...
For what it's worth, the original pump was made in poland, the new one in germany
