Its shaped but not that far from straight anyway, so you could use any kind of hose as a temporary stopgap. I think its 19mm or 25mm inner diameter, or something. Could probably stretch some garden hose onto the fittings, if you held the end in a cigarette lighter flame for a bit?

dipping the hose ends in boiling water helps soften them up too
