Howdy, I'm new to these machines and am nearly at the end of putting a new engine in, but I have a stray line in the water cooling that I can't find a pipe for. It's a small line that comes out towards the overflow bottle from a junction of large hoses from the top of the radiator and the top of each cylinder. More details here:

If anyone can help it would be most appreciated, just to let me know where this line leads to and how a long a piece of pipe I'll need etc.

Cheers
