This is a factory fuel rail that has been modified by removing the restrictive inner tube which results in a full 3/4" ID.  (factory is a tiny 5/16" ID). This new rail will support as much power as you can throw at it.
We can supply you with either a 5/16" ID hose barb or a 3/8" hose barb.  Just let us know in the notes section when ordering or email us.   Best part about this is that it retains the factory look (from the outside) but on the inside it will flow as much as any aftermarket (blingy) rail.  This is for those who like to retain the factory look while making more power.
 
This rail will fit all 1989 Chrysler TC with the 8v SOHC 2.2 Turbo II engine as well as all 88-89 Turbo I and Turbo II engines.
