AN16 works fantastic for upper and lower radiator lines. I use 16 for the upper and lower radiator hoses and 12 for the lines from the water pump to the block. I run a remote mount Meziere pump. Many street driving miles as well as track passes with no issues ever.
A remote mount pump is so much better. I keep saying I'll retrofit one to mine but for now I don't want to deal with the packaging changes and it'll be tight. When you have a Jesel timing belt, it makes the most sense but seeing the timing marks, priming the pump and service are some of the reasons as well.
