If it's metric find your local hose person and ask for a couple of Stauff GVxx fittings (xx is metric tube size,10, 12 etc) plus some equivalent metric tube. Or the joiner might even be long enough to replace the section you cut out where it's split.
Else if you can do without until you're at sea next send it tome while you're away and I'll have it waiting when you get back.
