Early square oil tank (2015)

Hi All,
Please, sure me wich one is the the breather and the ventilation.
Thank you.

The plain pipe on the left is connected to the engine breather. The tower on the right is connected to the air filter or to atmosphere.

Wait a minute. I've never seen a central oil tank with 2 ports on the top. I've got 2 types here, one like this.



and one like this



In both cases, the timed breather off the engine goes to either the port in the side of the tower or into the port on the top of the main tank. I don't understand 2 ports on the top of the tank unless it's custom made. Looking at my second picture, that hole that's in the air filter area goes up and ends in the tower thing near the top to keep oil from just splashing into it, it's the oil tank breather (the red line).

The first pic is earlier and the second later made, I think they had issues with oil from the engine breather going into the oil tank breather tube so they moved it to the main body of the tank so it wouldn't go into that breather and on into the air filter.

I think Piero is referring to the Fastback tank, not central.

Yes, is the Fastback oil tank.
It's so incredible the mistake I made when installing the oil pump gasket on the contrary (despite knowing the correct side) which now assail me all possible doubts.

Do you mean a tower and a separate breather spigot like this? If so, then it's the later design. The early tank with the spigot on the tower could blow oil into the air filter.
