Water leak 1.9 non turbo berlingo

[Berlingoshow]

    Hi all it's my first post. Have a w reg 1.9d non turbo and I need to fix a water leak. It looks like the hose end has perished at the engine block inlet. The hose I am talking about looks like it's been shortened over time. It's fixed to the engine block adjacent to the crank shaft pulley then it splits into two a y shape heading forwards towards the radiator and expansion tank. Does anyone know what part number I need to replace this? Any help very much appreciated.
