Hey guys, New Banshee owner here! I just bought a '96 and I've been going over it. I was tracking down a leak and came to a spot under the water pump, there's a brass-like fitting with a tube coming out of it. It's loose and actually came out when I tugged on it. Some oil came out of the hole. Now I'm freaked out! What goes here? Is this some type of breather hose? Thanks for the help! Matt This pic isn't mine, but you can see the tube and fitting I'm talking about.
