Annoying noise...lift pump?

[Mattinthehat]

Mine does the same, its the lift/low pressure (lp) pump - to confirm remove the seat behind the driver, make sure all windows are closed and radio off, when you switch the ignition you should hear the pump prime, by prime it should make a high pitched whining noise and you should be able to hear it working for a bit then it should cut off, it will also whine when its working..

You can try to sound deaden that area by putting something under the seat i guess...

If the noise is coming from elsewhere then i don't know!
