I have a pipe on the side of my carb, which looks like a breather hose, it is sitting below another pipe with is a small rubber tube which has a jubilee clip into a metal hose running To the fuel pipe, the pipe I need to know About has a small diameter and looks like a breather or vaccume hose, and I wanted to know if it is supposed to just hang down out of the way, or if it should plug onto anything, it's not the vaccume advance to the dizzy

It's a 1989 998 Austin mini running all standard gear

Thanks for any replies and sorry if it's already posted but I read around and couldn't understand/find what I was looking for

I believe there are 4 hose connections on you carb. The fuel pipe is easily identifiable. The small one above (ish) that one is the fuel overflow which usually goes to a metal pipe along the clutch cover (or wok) to the ground. The larger diameter outlet left over is a breather which should be connected to the engine breather canister. 

The tiny outlet is for the vacuum advance.

The fuel inlet goes to the float valve which is under junction of the Tee (see also the bulge in the casting by the screw). Any of the branches of the Tee can be used, sometimes 2 have pipes if the carb is one of a pair. The float vent is in the centre of the lid, so the pipe will point towards the centre and be the  lower one if there's a fuel inlet above. If you were looking at a larger pipe near the throttle, that's for the crank case breather.

Basically this is the pipe I'm trying to gather wether it connects to anything or just vents to atmosphere, thanks for your replies already

Sorry I was thinking of an hif carb for some reason. That's your fuel overflow which ideally should be routed away from anything hot. As I've said, it would originally go to a metal section of pipe which traces along the top and towards the front of the clutch 'wok' to the ground.

If you're lucky petrol will never enter this pipe. However, your were right to be concerned.
