Hey guys, I tried to pull off the hose that goes from the top of the water pump to the metal heater tube to "burp" the system after installing my 160* thermostat. The metal nipple that's on there snapped off when I barely tugged on it at all. Anybody know what the technical name is for this hose or where to buy it? Autozone or rock auto can't order it. Here are pictures of what I'm talking about.
