Kieron...this is the best pic I have, the end carbs are obvious, the center carb may be confusing as it has 3 ports on the passenger side, the correct port to attach the "tee'd" lines to is the port located in the middle, or the second one down on the center carb, the one located up top, or highest on the carb is the vacumm advance port to the distributor,...the 3 port or lowest, located on the base plate is for the choke pull off diaphram....hope this helps, the large 3/8" port on the base plate, located on the same side of the carb goes to the PCV valve, if your carb is equipped with a 3/8" top vent, oon the top of the bowl like the one in the pic, it goes to the breather nipple on the valve cover breather, if not using it, plug/cap it
