Hey ive been having issues locating a fuel line from the pump to the carb for my blazer. It has the 305 in it and I ordered the lines for the 4bbl carb and those weren't correct so I was wondering if I need the lines for a 2bbl carb or did those not come with them? Or could someone possibly put a 2 bbl on there later on and that's whats causing my issue in getting the correct line?
