Need help ID for part

[ScottyWM]

Had a catostrophic coolant lose last week in the E36 318is coupe (M42). Didn't notice until the check engine light came on (knock sensor), but appears to be no bad damage (oil is good, no smoke). Trying to locate the leak took for ever, but I finally found it. There's a tube that runs along the block underneath the intake that has a small hose that goes up to warm the intake (I guess). The nipple on the tube broke off. I've removed the hose in these pictures to make it clearer. Anyway, I have a couple questions:
1) Anyone know where to find a part number for this? I can't find it on RealOEM, although it does show it.
2) Anyone have a link or instructions on how to remove the intake on the M42? I'm going to have to take it off to get to this.

It's part of the engine block, don't you know? Germans..........
Looks like a joy to change too

Yeah, I found it. evidently it's a common failure point. And it is a royal pain to get at. Have to remove the whole upper and lower intakes, all the wiring harness connectors, even the alternator, to get at it. I'm doing all the hoses (air,fuel,coolant) while I'm there. Doing the same hose job on the M50 was about a 3 on a scale of 1-10, on this M42 it's a damn 8 IMHO.
