Fuel Tank Breather Pipe

I can see where this pipe goes into the  boot floor but I can’t see where it comes out. I’ve look on my other Manta and the Mk1 but it’s nowhere to be found. I can’t believe it terminates in the rear chassis leg!

Does any one know? I’d be chuffed if someone could have a look and let me know. 🤞

Not overflow by design, it's a breather, its to allow air back in the tank as petrol is removed by using the car and also to allow for any expansion and contraction of the fuel by heat/cold, and to let air out as you fill the tank up.

So, theoretically it’s sucking in fresh air and unlikely to eject any fuel into the chassis rails? I’m happy with that. 🙂
 

I have determined the holes are as follows;

1 - Fuel supply pipe to fuel pump/engine through rubber grommet/bung

2 - Fuel tank breather pipe sealed with mastic/putty 

3 & 4 - Fuel tank trim panel locating holes.
