All my fuel "noise" comes from the fuel pressure regulator in the engine bay.

Yes as I said I came from the walbro 255 and it was stupid loud (in my opinion). The walbro 255 is notoriously loud and is actually louder than their higher volume pumps. Google search it and you’ll find videos of it louder than an American muscle v8 exhaust and then switched to the DW and being whisper quiet. The walbro 255 is a vane pump most others (I believe including walbro higher volume) are turbine pumps.
