Dont forget to change the fuel pump and pickup tube in your gas tank.the fuel pump needs to be carb specific because carberators use a fuel pressure of any where from 4 to 12 psi whereas fuel inj uses from 20 to80+ and since the fuel pump is part of the pickup tube your tube will not reach after jerking the efi pump.You can buy new preformance oriented tubes but at the $190 price tag I would try to find one out of a carberated mustang at a salvege yard.Even a 4 banger mustang tube will work as long as its carberated.Also switching to carbed will simplify things once you have a grasp on the workings of the actual carberator it self.And dont let anyone tell you that carbed mustangs dont run well their are alot of guys running low elevens with mild street engines.
