Water hose routing 87 430

I am having an issue. I know the lower outlet of the water pump goes back up to the rear of the engine. The other outlet goes down by the exhaust to the y, then up each side to the bottom of the tanks. The problem I am having is The fitted pieces, I cant get the routing from the upper outlet to the y under the exhaust. I think i may be missing something. Does anyone have a close up pick of the routing?

Install the "Y" connector as in the image with the top of the "Y" facing towards the water pump.Do yourself a favour and install a stainless steel circlip to fasten the impeller to its shaft✊
