OIL HOSE RETURN 5/16X36
Return oil hose, 5/16 x 36, for routing oil back to the tank on unit Triumph twins.
This is the return oil hose, 71-7014, listed as 5/16 x 36 in the catalog — the line that carries oil back from the top end down to the tank on the return side of the system. It's also cataloged under the metric alias 8mm x36, so if your parts book lists it that way, it's the same piece.

It shows up in the catalog under both the gearbox inner cover and frame figures, which tells you it routes along the frame back toward the oil tank rather than being a stub fitting at one single point. On these dry-sump Triumph twins the oil doesn't just sit in the crankcase, it gets pumped out to the tank and back, so the return hose is doing real work every time the engine's running.
We don't have more detail on it beyond the size and the two catalog listings, so if you're not sure how yours is routed, give us a call and we'll confirm before you order.
