I would try running a wire from the battery directly to the fuel pumps and see if they run quieter while the motor is running.
If they do you know the MSD is taking power away from them the way it's wired now and you need to rewire them with their own fuses directly from the battery instead of the from the fuse box/relay panel 12 volt bus. You can do that and still use the 2 red relays to switch them on and off.
