Norton Tube (3.375 in.)
A 3.375 in. tube from the oil tank and oil pipe lubrication system section of the parts book.
This is a tube listed at 3.375 inches, showing up in the parts-book section covering the oil tank, oil pipes, junction block, rear chain oiler, and full flow oil filter. That figure grouping puts it in the oil delivery side of the engine's lubrication system rather than anywhere electrical, so don't let the manufacturer code on file fool you into thinking Lucas made this one.

The catalog record is brief on this part, showing up in only a couple of listings across the early 1970s span in our books. We don't have more detail on it beyond the length and the figure it's grouped under, so if you're trying to match it against what's on your bike, it's worth double-checking against the physical piece before you order.
Call the shop and we'll help confirm fitment and placement in the oiling circuit before you commit to buying.
