Well that is stupid! I see the relay on the fender for the switch you had down by your steering wheel but I have no idea why they put that valve on top of the fuse box???? Are you sure its not mounted on backwards or something from when someone else monkeyed with it? I am not at all familiar with the 6.4 under the hood.

I don't think this is OEM, but if it is, the engineer is related to the idiot who designed the motor oil filler on my 1990 460.

My engine compartment is not set up in the same fashion on my 2010 6.4 PS.

I searched the net for pictures of 6.4L engine pictures and also checked Powerstroke sites for "fuse box", and like you saw engine compartments that were not the same as his. I also found no complaints for "fuse box".
I am with you thinking its something not OEM. It would be interesting to find out what it is and compare it to the engine compartment of a OEM 6.4L. Maybe you could take a few good pictures for him.
I am wondering if the truck was not wrecked and put back together differently? It looked to me as if not even the coolant recovery tank on his is in a different position. On his there is a hose clip that is not used, on all the others I seen had a hose in that clip.
If it is OEM, its a stupid design.

I'm told this:
"it provides the vaccume for the auto hubs if it has them and if it has manual HAVC controls it uses the vac for the mode motor"
Just heresay, though take it for what it's worth. I don't own a 6.4L and don't claim to know everything about them.

The contraption starts with the steel bracket to which the fusebox is mounted. On the front side (front of vehicle) of the bracket is a captive nut for 1 bolt that holds the outboard end of the plate to which the actuator is attached with 2 or 3 seperate bolts. The on the Inboard end of the bracket (after wrapping around the bottom of the fusebox) is a tab about an inch wide which has a slot in it. The plate under the actuator has a tongue which inserts into the slot and is then secured with the single bolt mentioned previously.
The way the thing has been made, it would probably have taken 100k or more of tooling to make the stamped parts and then the captive nuts (3 or 4 of them) have to be projection welded onto the different plates, and then someone has to be paid to assemble the whole mess.
Looks to me like it was something that was forgotten or added at the last minute and Ford decided ***that*** was the best place to put it.
To change the battery in my wifes 97 Venture was a job that took more than half a day and cost most of my knuckleskin... The air filter box and PCM had to come out to allow the battery to be changed...
I guess I will have to figure out what the device does and look for a better place to put it. There surely has to be a better place than right above the fusebox. Many people may never blow a fuse, but for the time that someone does, it is a real PITA. The other thing that I learnt was that about 3 different geometry of fuses were used, so I had better get a few spares to cover me while out on the road.

I guess the thought never occurred to me that it might be a vacuum pump. The cylinder could well be a motor and the lines do look suspiciously like vacuum lines. Do the brakes on the PS models need vacuum for a servo or not ?

You should have a hydro boost system for the power brake assist. This system relies on the power steering pump for fluid assist pressure. I am 99% certain your 6.4 will have this system, but I will peek under the hood of one of our 6.4 work trucks tomorrow morning and report back tomorrow night.
