This board is sooooo cool! I just pasted the adress of the image and it displays the image. Coolsome!
Anyway, that picture is of a *generic* banjo fitting. The one on the manifold is the same thing except that the hose is rubber and it plugs into the backward side of the manifold.
Don't know what kind of engine it's from, either... not an MB diesel, that's for sure! :^)
