I stripped my MAC 3200 to get at the tubes and most were broken. I have new tube but need to know which goes where. I presume the filtered gas goes to the bigger metal tube on the carb and then another pipe goes from the carb to the primer but I don't know which of the two primer connections it goes too. On the primer there is a short connector and a longer one which of these connects to the pipe from the carb.
The short one, this is a suction tube and pulls fuel from the carb and into the bulb, the long pipe on the primer pushes from the bulb and back into the fuel tank
