Here is the FBH parts list but I don't see the hose you need on it:

From the pic you posted up it, you need the hose with the bleed screw - its about 12-15inches long. There should be a joining for it on the near side of the FBH.
I have one of these hoses if you want it but if I was you i would buy a new one. A second-hand hose may be perished and you could be back where you started in a few months. I'm all for saving the pennies but with something like this you are better off with a new part.
