Unless the pump assembly you remove has a really nasty primary filter sock there should be no need to flush the tank. Some new pump assemblies do not have the floppy sock at the bottom - the primary filter (strainer) is internal.
Some pump assemblies also have an upgraded HD electrical connector that gets spliced into the existing harness. The wiring diagrams for various models are included.
Airtex, AC Delco, DELPHI and UltraPower are all OEM pump assemblies in different boxes.
