Cobra R Secondary Air Injection Pump

Can anyone tell me more about the P/N F6ZE-9A486DC Cobra R secondary Air Injection Pump . I've heard of people using these as a crankcase evac pump on other applications. I have a 5.0 with a vortech and a leaky rear main seal under boost. I was really interested in this particular pump since it is electric and an OEM part for a Cobra R

Anybody????
