I've looked in the mini/metro books and can't see what the large black plastic bit if for The fuel inlet I assume at 2o'clock to it but not sure of the other two inlets/vents below [frame][/frame]

The black box is a vent. The pipe at 2 o'clock is NOT FOR FUEL !! It is the intake for drawing the horrible fumes away from your engine crankcase via the rocker cover breather pipe....... The fuel intake is the lower of the two smaller pipes - and the other is an overflow in case of flooding. Don't block it!
