The fuel system is different, but only early 99s have the return style. Late 99 on up has returnless.
There is also a difference in the timing cover and belt routing on the 01/02 cars, which probably makes a difference because of the way that the Vortech mounts, and where the jackshaft pulley is. I'm just guessing here...
Good luck finding one anyway. If you want a supercharger kit, the best thing to do at this point would be to contact Blackcoog and buy his kit when it is available. You can read about it here:
Just giving Vortech crap for stating '98 in their advertisements. And like Wade hinted at, good luck finding one since they stopped producing them last year. Hit up BlackCoog when he is ready for sales.
