Do I need this?

Thought it was part of the braking system maybe for changing the rear to discs but turns out it was connected to the fuel tank (check valve) winds about like a snake but is blanked off at the end with a rubber cap. Do I need it or can I just blank it at the check valve?

Looks like a breather pipe to me, shouldn't be blanked off because your pump could collapse the tank when it removes the fuel if air can't replace it

As above, you need a breather, it doesn't need the be that big though.

Cheers, had a look at the Haynes manual and says it's for the evaporative fuel flow to escape and the air comes in through the filler cap valve. So if I add a shorter piece of plastic pipe (enough to keep it away from the wheels) with a filter to stop debris getting in thatl do will it? Really confused me that was thinking what's the point of it if it's capped at the end

You can replace it with a fuel resistant check valve and a small length of pipe.
