I've changing my system for a swirl pot so changing the fuel lines, the wiki states I should have two - supply and return. i've found a third and unsure if I disconnected it for something or it's a breather hose? It seems to be open...

Image

This is where it starts, to the right of the bracket from the tank / rear bench, and if you follow it to the most left crimp on the rusty line it goes down the sill:

It goes up through the bay beneath where the other two lines were (now up for sale!) into the rubber hose. That hose I found tucked behind the wing. Just making sure that wasn't me forgetting to do something with it, is it a breather? What do I do with it regarding my swirl pot, anything at all?

Image

*Seems* to be one of these, can't tell without dropping the tank (I *really* don't want to be doing that if I can help it...)

Image

Also what do I do with these, nothing at all? I'll be going from the low pressure pump:

...feeding the swirl pot in the boot. This then has a high pressure pump to the engine, and takes a return. It will have it's own return feeding back to the return line of the tank.

Cheers as always!

Vent pipe for the tank, going forwards to connect to a closed circuit tank vent system if fitted.
Not required in the UK, so can be chopped back to the LH side at the rear, as long as you make sure there' no chance of the end getting blocked.

Thanks Brian! Just wanted to double check I hadn't been stupid....

Is that to equalise the pressure as the fuel goes down? Do you reckon cutting the rubber tube (1st picture where the bracket is) so it points backwards would suffice?
