Was the intake manifold changed at all from the 98 and newer compared to the 97 and older?

I need to know if the older return line style fuel rail with fit on the 98+ Zetec manifolds.

I'm using a 99 Zx2 Zetec in a car with a return line fuel system, All Zx2 have the return-less fuel systems, not compatible with my managment.
Thanks
