we are just getting our little smokey ready for vanfest!!!!

and we noticed a date on the gas bottle rubber pipe, it is dated 2001.
googled this and a few websites say, it needs to be replaced.
can this be done by anyone or do you need a specialist gas fitter to do the work?
the pipe goes from the gas bottle regulator onto a brass pipe, and then before it reaches the gas cooker, then into a rubber pipe for the cooker and fridge.
what do you think, safe to do yourself or get someone else to do it?
don't fancy being blown into next year at vanfest, don't think the neighbours would appreciate it!!
