Good info guys, keep it coming.

I think my problem with noise was my gas lines, not the pump. Let me explain, I had the pump mount isolated with rubber and actually hung the pump by plastic wire ties from the mount and the noise did not change. I can really hear it coming from the left rocker area (where the fuel lines are). I put rubber hose around the metal lines along the length of the car but that did not help. I think it the volume of fuel flowing through the lines that's making the noise, not so much the vibration of the metal lines. Maybe I should try another type of electric pump.

I don't have a regulator but I do have a return line.
