Coolant pipe and hoses

The 2L engine in my Tipo has a delta water pump also with the delta metal pipe that runs under the inlet manifold. I think this pipe is different to a Tipo or Tempra etc pipe, anyone know?

Im trying to figure out the best way to run all the coolant hoses, Heater, header tank etc. The pipe to the header tank is currently too small so its not a good fit. Im wondering if there is a better way. Does anyone have any ideas or have any pictures of a factory tipo, tempra etc coolant flow diagram?

Cheers,
