What is this tube for ?

[Hedgehopper]

Can anyone tell me what the upper rubber tube is that's protruding from the inner wing behind the windscreen washer bottle (above the charcoal cannister pipes)? Just noticed in the pic.that the bottom hose spigot is leaking - another job!

Make sure it can't suck up any water as that's a recipe for crud running in the wet.
