Derek is this it?

The only hole with anything plugged into it is the one pointing to the side.  I had found a random, rigged ass up line that was just hanging, but I assumed it went into the open port on the valve cover pointing on the firewall, and it plugged into there fine so I assumed that was right.  Now I'm thinking that it actually should be plugged into that hole on the manifold.  I'll try it in a few.  It doesn't have the elbow that Jeffro pointed out, but like I said, its pretty well rigged.  It has a solid metal 90 degree, then some shitty rubber line that was cut up, making for an elbow.
