The only things that come to mind is that the last Shurflow (a SHURflo Whisper King
) I bought came with an inline strainer, so you don't need to buy one separately. It also has great isolation mounts, so I don't see the need for the bed of rubber assuming you get one with good vibration isolating mounts.
You may want to look at flexible lines
from the pump to the hard plumbing to stop vibration transfer that way.
While it may sound like I'm not concerned with vibration transfer, I am. I mounted my new converter
with rubber mounts. My self installed built-in subwoofer, too. I just haven't found it necessary with the SHURflow pumps, especially using flexible lines between the pump and pex.
