Pipe diameter

How do!

The thin hose that runs between the expansion tank and the top of the radiator on my 1800 8v clipper is leaking a bit.

Anyone know the internal diameter? or general pipe size?

Just being a daily driver, if i take it off and the local motor factor doesnt have any ill be screwed.

Many thanks in advance!

Mine's doing the same, not got any new yet. Seen this post, and gonna trust the last reply and get a 6mm internal diameter one. Sounds about right. http://www.vwgolfmk1.org.uk/modules.php?name=Forums&file=viewtopic&t=67184&highlight=header+hose

cool!, will buy some at weekend

After more careful inspection the radiator was leaking as well as the pipe!, anyway replaced both, just waiting for a new set of hoses. May as well do the lot.
