In fact when i had the housing done I had the main hoses changed as they were the original on the car from the factory (despite an engine change from jaguar in 2004).
I was honestly surprised at how much the old hoses were 'bloated' compared to the new ones. I understand that it is possible to buy kevlar type house from some suppliers that should give a longer life...hhowever I think 13 years is enough
