Hi everyone! This is my first post here. My dad and I have replaced the cylinder head on my 2001 focus 2.0 sohc spi. We have everything hooked back up except for this one hose that is connect to the intake manifold. We can't find where the other end of it connects to. I have searched everywhere but we are stuck! Can someone please help? We un hooked the hose and got these numbers off of it 98AB 18C266. Any help would be greatly appreciated.
