fuel pump making noise

[peanotation]

my walbro 190 fuel pump has been in for a few days now with no problems, and just today it started making noise. the car runs and feels fine, and the a/f ratio is bouncing around as normal. ever since i put in the new fuel pump, the car definatly pulls a little harder, but this noise is frightening me. i don't mind it, as it's not loud at all, but i'm worried something is wrong. it sounds like a mechanical whirring, and it holds the same not, and doesn't change pitch at all. when i put the car into Reverse from Park it changes pitch momentarily but goes back to the scary whirring sound. any help would be appreciated.

Pretty sure its normal. I know the Walbro 255 is very loud. Dont know much about the 190.

Yep, I've read many a time the added noise is normal.
