Perhaps two versions? A cheaper tapped hole version, and a more expensive version that has some isolation?
I wouldn't worry about it to much, most of us spl anal retentites will find some convoluted personal "best" vibration damping method, or just hang the pump from the tubes. Threaded holes are sufficient.
