Based on what you are saying, you are correct. Your mechanic is describing the heater inlet pipe (number 8 on your drawing). You should replace the other plastic pipe (number 6) while you are in there, since it is accessible. You just need to order the pipes. They usually come with the o-rings already on them, so that can save you a few bucks. For both pipes, you should look at about $75US. It is just a matter of where you get the parts from and the shipping cost.
