Video is with the car on and running.

It is a dual pump system. I am 100% sure sound is coming from the external in-line pump, right infront of the back drivers side wheel where the fuel filter is. I am trying to figure out if it is working that hard because the pre-pump in the tank has failed, if the FPR is out of wack, or if it is just the external in line pump that is bad.

Briefly swapping out the external fuel pump would likely answer those questions for me.
