I just wanted to reclarify what has already been said.
Reg gets fuel after rails before tank return to clarify. Sorry for confusing you all. I just finished some fuel system removal on an sti and figured to mess around on the forum a bit. didnt mean to cause a mess. I have sti fuel parts for sale in the private fs forum if anybody would like some low mileage stuff.
