Does anybody have that pipe part # or something so I can call a dealer and figure out what was that?
You mean the big hose connected directly to the oil filter housing? There was no gasket as I remember, just the metal "ring/clip" that held the hose in place. If the metal ring/clip is still there I think you're ready to just put it back.
