Pump noise after shut down

[07lariat]

Whenever I shut the engine off in my truck I can heard what sounds like a pump run for a minute or so. Anyone able to tell me what it is?

Vacuum pump??

Thats an old Ford program that has since had an updated version. I think it runs after the truck turns off to pressurize the fuel system to help with starting. Take it in and get the latest software update.
