You'll only need the hose kit if you are using a "proper" regulator (although other, cheaper, solutions are available). If you're using the regulator supplied with the 160TM the thin white gas hose fits straight in. The standard hose is long enough for small and medium bottles but would probably struggle to reach a full size bottle.
You mean Clarke don't supply a 'proper' regulator? Good lord, what do they charge the extra dosh for, over the TE? Plastic case?
