I've got a high pitched squeal coming from somewhere around my muffler. Any ideas?

When? During drive, or while stopped? The fuel pump is not really all that close to the muffler..

Default Which side? The fuel pump is closer to the passenger side of the car..

you should hear a muted whir or hum from the pump.
