What Fuel setup are you running

I've run a few different pumps and had varying results.

The in tank pumps are silent, just like a brand new car.

I've run an Aeromotive A1000, quiet

Last is a holley black. YOu can hear it a little, but it is very mild.

I'm sure it depends on how, and where they are mounted, as well as how much sound deadening work you've put into your car.
