My 1980 ( february) FJ45 does not have the original carb on it and 3 line fuel pump with return . I would like to go back to stock or at least back to Toyota. I have 75, 77 and 78 carbs which have the return line from the carb and 2 line fuel pumps that I know I could use but I am just wondering if anyone can tell me if a 3 line FP and single line carb is stock for this year?
