The original pipe 964-423-109-01 was not in stock at Porsche Norway, so i went to the local hydraulic stockist. They made me a hose instead capable of 320 bar. They did not have the correct nipples but the threads were correct.
I hope Loctite hydraulic thread sealer will make it leak-free.
Will know in a few hours. :)
