I just started noticing a sound coming from under my hood yesterday. This morning I woke up and checked it out and it's def a new noise that is coming from the area behind the fan where the belt meets the alternator. It sounds like a card in bike spokes. I posted a video of it below. Any thoughts?

Tuff to tell but the High Pressure fuel pump is in that same area and it could be that.
