If memory serves me correctgly (and it rarely does anymore) that piece goes behind the oil pump and is what connects the oil pump (outside the center case on the R/H side of the engine behind the clutch) to the pick up (insice the centercase). There should be a smooth hole and a tapped hole with nothing in them...

That pipe runs between the crankcase halves, and and feeds oil to the transmission bearings. Without it being in place, the oiling system may suffer an overall pressure loss, as well as obvious transmission problems.

It is installed from inside the primary drive cavity on the right side, adjacent to the point where the external oil line bolts to the crankcase.
