Non-HO 89 to HO 93 motor swap - fuel rail questions

I am swapping my 89 motor out for a 93 motor.
I have both entire Jeeps.

I am wanting to keep the 93 intake and fuel rail.
Can I just pull the 93 fuel lines and replace the ones on my 89 since the newer fuel rail has the lines running differently than the older one?

Is there anything I have to modify to make this work or is it just bolt the new lines on?
 
Did this on a friends XJ (put a 93 in an 88), you have to swap the whole manifold, the throttlebodys and linkages are different. We had to use all the old intake/exhaust stuff, just swapping rails won't work.
 
You can swap the lines back to the tank.
OR
You can cut the lines at the firewall and use a pair of couplers (unions) to join the 93 front lines to the earlier back lines.
