The mod was easy and quick and not all that costly with readily available items for home supply or hardware store.
Two 20" FIP sink hoses were required to make the loop back to the pump from the exiting pex connections. Existing pex connections require a 1/2" x 1.5" or 2" threaded nipple with the ends c'sunk to remove sharp edge.
I mounted the pump on either 3/8" or 1/2" rubber air hose for more isolation from the floor. 12" was enough to make 2 isolators and 4 #10 scr's, nuts, FW's to mount pump to hose. It is now so quiet, that it only makes a hum.
Below are a couple of pics of the installation. Not the neatest, but was installed during the FL summer in haste.

Nice mod. I have always found that mounting surfaces of components and the associated vibration contributes quite a bit to noise.
One this I notice, or don't notice, from the pictures is the lack of a water strainer. Is there a strainer somewhere else within the fresh water system?
