[C320-list] Yanmar hose replacement?

[Scott Westwood]

I have not tried a simple clamp replacement or just reclamp (yet...nipple cold have pinhole?) but IF.... I need to replace the hose from the raw water pump to the heat exchanger does anyone know if it requires a specific part?  It makes some complicated direction changes. I can't see making stock hose stay bent that shape?
FWIW I have small leak at the entrance to heat exchanger at the top of this  hose
