I currently have a problem with my CPR fuel rails. I am running a return style fuel system with a billet spacer (i beleive 1/4 inch) underneath my 2.4 KB and it will not allow the rails to properly mount. It seems that there is a gap between the fuel rail and the injectors. Does any else have this proeblem? If not, what rails are you guys using with the spacer? Any help will be greatly appreciated.
