Today, the rich sum of £42 was spent on a Mocal Fuel Breather roll over valve, which cleverly allows air to go in/out of the fuel tank but prevents fuel spilling out if the car becomes inverted (not expected in normal driving conditions)
A nice little safety feature and when I say "little" I mean tiny! The barbs for fitting the hoses are 7mm wide so the whole thing is minute.
It'll look a lot better than the plastic tube loop I have at the moment (which will work but doesn't look anywhere as good)
