So I tried it today and noticed that it doesn't do it when I put the key in to start it up, but instead only when I remote start it. Wonder if it's maybe the starter? [emoji2371]

Ok, I thought maybe the HPFP primed before starting.
The sound only happens when the truck isn't warmed up.
And no the sound is definitely coming from the engine bay. The primary filter/pump area just makes the standard sounds.

I've done a good bit of googling and all but just trying to confirm that this sound is the HPFP and that more than likely it needs a new filter and o rings. Just wanted to see if anyone could maybe confirm this before taking it in.
It makes the sound when the pump is priming for 15seconds or...
I actually just got a F350 a few weeks back and had the same thing come up 100miles after driving it. Took it to the Ford dealership and they checked it for free [emoji2371]. May just depend on the dealer. I was able to read all about this though with a quick Google search.
