I just went out and had a look at mine, yours looks a little different (I have the BWA engine) but it seems to be the fuel line TO the engine.

Fuel line. At the metal base of it behind the coolant reservoir should be a coloured ring either red or blue. One is flow the other return, can't for the life of me remember which is which though!
