I even insulated line out of pump and under header system connected to pump so nothing vibrates on glass

The vibration is where you'll be getting most of your pump noise. The flex PVC helps a bit (as compared to rigid PVC), but you can reduce a lot of the vibration by putting a section of vinyl tubing (at least a foot) right above the pump. I use the anti-kink stuff but if it's a straight shot it shouldn't matter. As for underneath, if it doesn't have rubber feet, you can make your own with a bit of silicone. And I've heard of others using mouse pads underneath, but I probably wouldn't chance it. You should be able to find a good inert rubber mat (or rubber feet) somewhere. Or use some 10mm neoprene.
