You are Way off base.
The injectors just mount in the LIM. You would just use your old injectors and fuel rail.
It's called a "Returnless LIM" beause that's what type of fuel system the engine has that it comes on.
That is also why I state looking for a 00+ Cougar is the easiest & safest way to find a used one.
You should be safe looking for a 00 Contour/Mystique LIM as well. (provided they LISTED the LIM correctly and DID NOT mass group all the years!)
