Here is the OEM part # 19505-PJ0-A00 (may vary across sub-models) - Number 12 in this diagram Part Detail

But I doubt you will find this part anywhere besides a junk yard. It's a metal pipe with a few outlets on it.

you are missing the extra outlets on the water pipe right? if you know anyone who can braze, the pipe is steel, it comes off but you will need a new pipe to water pump O ring, or just see if someone on here has an extra LXI pipe and swap it out
