Need help choosing new fuel pump

[davbell22602]

2004 ford f350 5.4l 4x4 regular cab 8 ft bed one gas tank super duty xlt.

Will buy it from rock auto. Nobody local has it in stock. Napa told me there's 6 different fuel pumps. Difference is GPS (gallons per second) and something about the length. Not to take old one out due to not having a 2nd vehicle to drive to work.

I like to call the dealership parts dept. with my last 8 of vin and have them verify me the part # in these situations.
