    The only difference between the three is where the inlet and outlet holes are. They are all the same lph and pressure.

    GSS340. Don't buy from Summit. You won't get the correct pigtail.

    GSS340 is the correct pump for all years as long as they are a fixed voltage pump (your 04 is). Just make sure whatever company you buy from includes the wiring pigtail.
