  Will this work with a fass 165, im looking into doing a sump or draw straw to stop cavitation but would like to go this route if it will make my 165 quite

  Yes, it will work with your FASS 165 - it will help quiet the pump and reduce cavitation, eliminating the need for draw straw or sump.

  Does this eliminate the need for a lift pump such as fass or air dog??

  No, the SureFlo Performance Sending Unit does not eliminate the need for a lift pump like a FASS or AirDog. It improves fuel supply to the CP4/CP3 by upgrading the in-tank pickup and delivery system, but it does not pressurize fuel like a standalone lift pump does.
