in process of getting my 67 up and running again. gas tank is full with 10+ year old gas so was planning on dropping and maybe just replacing the tank instead of trying to clean it... came upon the aftermarket setups with a fuel pump inside the tank for efi applications.. would this work on a carb vehicle still or would i run into complications i know i would have to add a fuel pressure regulator and return line but would like to get away from the mechanical pump and just go full electric fuel supply. Has anyone done it and can chime in?
