Can anyon tell me what this device is on my 03 7.3L Super Duty E450? I've looked through my 2003 shop manuals and have not been able to find it. It does have a small leak I can feel on my hand when the truck is running. I sent ther pic it as an attachment. I hope the pic made it. Thanks for looking.

Vacuum something or other?
Where is it at on the motor?

On the front left side. As you can see it's belt driven. I can hear it leaking while the engine is running.

I believe your correct. Thanks for the input. I know it shouldn't be leaking so it's change out time.
