A3 Coolant Leak (caused by fuel leak?)

Our A3 has been leaking coolant for a little while since the fuel pump gasket went out and leaked fuel. I've been trying to find a replacement hose before i dig in and fix it however i do not see any hoses in any stores online or anywhere. The only coolant hose parts i find are that big plastic flange. I seem to remember hose part mentioned that you should replace with the fuel pump gasket however i can not find that thread . Also, here is a big hint, since it is warmer it leaks much less.

Does anyone know what hose i need. thanks for any help.

All too common with a diesel fuel leak. Below links may help.
