2007 C280 hot water lines.
 

I'm trying to rebuild the hot water lines for heating in 07 C280, and need help identifying missing parts. I've got heater core return figured out, what i'm missing is the feed. On the diagram attached - numbers :
10, the T where 15 and 30 are attaching, 155 and 50...

Could anyone post pictures and/or part number of feed line to the heater core, before the waterfall?

Thanks!
