Lately I've had this wierd humming/moaning type noise coming from the truck. Its the most noticeable at an idle when the motor/exhaust isn't very loud. If I give it a little bit of throttle it kind of speeds up with the motor. Can't figure out what it is.

$20.00 on the fuel volume control valve. 3 of my 6.4's do it, 1 doesnt. Just an educated guess!

probably not it but if you upgraded your cold side pipe check that to make sure its not rubbing/vibrating the core support i found that making a noise as well
