Irritating buzzing

[rekless315]

I only have about 9k miles on my truck im tuned and deleted. I recently developed a very irritating buzzing noise that sounds like its coming from the drivers side front wheel-well. Anyone know what is causing this or how to fix it?

[SuperCrutyPS]

Have you taken it to the dealer to ask them?

[rekless315]

Not yet im a little worried because im deleted

disconnect a vacuum line up top, it'll go away. i've seen many with vacuum pump issues cause this. so many in fact that the part is on national back order

[rekless315]

Just disconnect a random vacuum line? And that doesnt affect anything else?

[strokemyego]

it does it when the truck is not running too, am i correct? there is a vacuum line up by the degas bottle. won't effect anything as long as you plug it back in. you can do it with the engine off if you feel more comfortable, than plug it with your fingers. but if you don't feel comfortable touching it, it is covered under warranty and your dealership will put you on the waiting list for it. its not doing any damage

[rekless315]

Ok ill try that

[strokemyego]

thats my fault, its the vacuum solenoid not the vacuum pump, and we got one in today, so i'm assuming back order is over

Sounds like the hpfp, mines going out , try putting your hand on the upper fuel filter just above the drivers side head and hope its not violently vibrating like mine, ford said my injection pump is going out

Try changing the fuel filter. Mine had the same sound and hasn't been back since I had the filter changed.
