Vent pipe
Vent pipe for the oil tank, letting the oil system breathe as pressure and level change.
This is the vent pipe that runs off the oil tank, catalogued under 57-1579 (also shown as T1579 in the older letter-prefix numbering). It shows up in the parts book across the Oil Tank and Petrol and Oil Tank figures, so it's part of the oil system's venting rather than anything to do with fuel.

On these tanks the vent pipe lets the tank breathe as oil level and pressure change with the engine running, keeping the system from building unwanted pressure or drawing a vacuum. It's a simple piece, but a cracked or misrouted vent line can mean oil weeping out where it shouldn't.
Our catalog record ties this part to oil tank fitments spanning 1960 through 1969 without pinning down a single model, so check it against your tank before ordering.
