I have a heater hose on the drivers side of the car (an 86 328GTS) that disappears over the gas tank to never never land. I have owned the car since new and, believe it or not, have never changed the heater hoses in the 38K that the car has travelled. As far as I can tell it looks like the gas tank has to come out in order to replace the hose but, of course, I have no manual that details the hoses or their routing. In fact, I have looked at nearly every manual available on the car and I don't think I have seen one that shows the hoses and their routing. I think I need to dive in and change every hose since I have had a recent pinhole leak near the block that I rigged by shortening the hose and reconnecting. I know I am gambling with these hoses. Should I do the obvious and remove the tank or does someone have a brilliant shortcut? Also anyone ever seen a source for something like a hose kit? or should I just go to Autozone and try to get close?
