electric fuel pump

Let it be known almost all cheap ($120 or less) electric fuel pumps sound like a freaking chain saw running. I had a Holley blue pump on my car at first and even though I had it mounted on a thick piece of rubber it still drove me crazy. I could hear it over the headers with dual cherry bombs. After that lesson I only run a georotor style pump or a mechanical pump. As for pressure anything between 3 and 6 is perfect. When you get much over 6 psi it can over power the needle and seats on a AFB causing flooding. Holley's seem to handle more but Carters and Eddy's don't care for it.
