Different parts. If you look at that pic in that link I gave you, you will see the vacuum pump next to that football looking holding tank. lol
EDIT: When you turn the key on, you will hear the fuel pump come on also. The fuel pump is under the cabs drivers side. Kind of right under the front door on the frame rail. Is this what you heard???
Passenger.I'm thinking that its the a/c, but could it mess up something electrical? And also, on the passenger side there is a ring that is out of place. Can I post pictures?

The vacuum lines going to the hubs don't go under the ac. That is maybe the line going to the blend door. The lines I'm talking about come from the solenoid to the front hubs.
It would help if you could post pics. I use photobucket to post some of my pics.
