I'm in the process of putting my ratlook 240z back to su's and have a question regarding the fuel rail. I would like to tidy up the engine bay a bit and am considering not using the factory rail/return arrangement. I'm running a red top electric fuel pump at the back and was intending to feed both carbs directly and have a restricted return off the last carb. So in effect it will be pump to engine bay then T off to one carb, T off to second carb, then restictor in the line going back to the tank. Does this sound correct? should I fit a regulator or will the carbs hold back the pressure from the pump. What size restrict will I need? all help or advice appreciated.
