I will check and report here.

I learnt from a colleague at work that it is a gas tank breather tube.
As gas is pumped out of the tank a vacuum is created and air is pulled into the tank through that tube.

Also, the line coming out of the intake-manifold is the for vapor or moisture release OR as you mentioned some sort of emissions thing where vapor is fed back into air-intake for efficient gas mileage.

The line from the gas tank goes into the black thing which has 4 holes (is this what is challed a charcoal canister?) and the line coming out of it has a different diameter compared to the air-intake line...

I shoved one into another and secured with gorilla tape...
