'98 Fuel pump different?

is the '98 fuel pump different than other years for some reason?

i just did a search and didn't really come up with anything. I also checked summit and couldn't really find anything for that year in V6...

I though our cars had the fuel return so i figured any year mustang fuel pump word work and any lph... but am I wrong???

some shops are saying that there's a special "California" model that has strict emissions standards or something.

What kind of fuel pump can I buy?
