The hoses appear to be for fuel only? Please bear in mind that the hoses used for your water system are reinforced due to the high pressure in your cooling system where as the fuel system are not?
There may be pipes that can do both water and fuel but worth a check?
We use silicone hoses in our water system with stainless jubilee clips/clamps.
