There's a strange tube sticking up in my engine compartment and I can't figure out what it's for. It's the one with the white cap that seems to have a vent valve on it. It's in the middle of this picture:
My problem with it is that the other end isn't connected to anything. I thought it went to my clutch, but I found that hose and confirmed that it connects to the clutch. The end has some sort of metal elbow on it. What is it?
I'm also having trouble on the correct procedure to bleed my clutch. The pedal only seems to have the lower half of the normal range of motion and it feels a little soft. Any direction on that would be great. I think the previous owner just replaced the clutch master cylinder.
