are all the fuel pumps interchangable between the years?

just like i asked. are they all the same? (upgraded from 08's i mean)

i'm looking at keeping my currently working pump in a box for my wife to ship out in case i get stranded, and upgrade to the newer one.
i don't have a ton of miles (6k) on it, and it still works great, but have a big trip coming up that i'd prefer not to get stranded on!

from what i can tell, they're all the same part # now.

i figure i'd order one for an '11 to get the newest pump available?
