So just to wrap this up............
I decided to give the flexible pipe a bit more clearance.
Here it emerges from the union horizontally......

So I broke out the Dremel with cutting disc, and it made short work of the modification.


While I was at it.........
I just couldn't resist finishing off the holder-downers. They needed a bit of rounding off with a file. Not so good as the 2005 versions. Then I found some fine leather, and some glue and this was the result.

Very thin leather will wrap over the edge and stick.
So that's it. Job done.
