Rocker to oil cooler flexible pipe
Flexible oil line running from the rocker box to the oil cooler, PN 70-8906 (alias E8906).
This is the flexible oil line that runs from the rocker box down to the oil cooler, part number 70-8906, also listed under the earlier E8906 designation. It shows up in the parts books under the OIL TANK figure, which places it in the engine oil circuit rather than the top-end lubrication feed itself.

A flexible pipe like this lets the oil cooler mount somewhere away from the rocker box without needing a rigid line bent to match, and it takes up the small amount of engine movement relative to the frame. Being a rubber or braided flexible section rather than solid pipe, it's the kind of part that hardens or cracks with age even if it looks fine sitting on the shelf.
