That's a valid concern.
No, I've not contacted Red Dot. Honestly I don't expect them to be helpful and/or charge government prices. They probably want $200 for that bag of parts, if I'm lucky.

You can use the blower hose adapters from the heater unit so don't worry about that. You will have to bend the tabs a bit and crush them oval to get them in but it does work and in fact I had to do this on the passenger side due to the proximity of the transmission control unit.
I looked in the IETM's and the PDF's I have for the LSAC FMTV's and none of the parts diagrams list that drain tube. In the IETM it shows it as item #59 but does not give any part numbers for the breakdown of the heater/evaporator HVAC unit.
I would call Red Dot. Can't hurt to ask. Just explain that you are such and such unit motor sergeant and are in need of a part number and NSN since your manual doesn't list it. Positive they will respond to that

Yeah, I've tried multiple search engines, and found surprisingly little that would fit the 15mm hole.search of the net for "rubber duckbill drain" came up with.

so it is 15mm OD hole?

The hole is the bottom of the HVAC unit is 15mm, I'd call it the ID, but I suppose it's also the OD. There's not anything protruding out from the sheet metal that I would call an OD, just a hole.
And there are two different thicknesses of the metal around the holes. I was able to get a grommet into a couple of them, but I did not have a grommet with enough thickness to get into the other pair of holes, as the HVAC unit's floor was twice as thick in that area.

I did find this:
https://www.amazon.com/gp/product/B0016HYTBM
Which looks like it might be easy to modify to do what I need. I might have to trim the diameter a bit, and probably glue it in place, but it looks like it might be made to work.

2 pin orange and black is 24v power from PDP. 4 pin goes to the original power connector the heater used.

Thanks Tom, but I actually found mine tonight. The bag of goodies got shuffled into another box of LMTV parts and I stumbled on them by accident.

All,
I am temporarily stalled. After I drilled out the hump cover, the sewing split open (unrelated). I sent it to a repair shop today and should get it back next week. After that is done, I should be ready for the evaporator install.
Real quick question…… I put a zip tie on one of my heater hoses to remember which one was feeder and which one is return. Now I don’t remember which is which. I am assuming it will be obvious, but since my cab is down for now, I thought I would ask for an easy way to identify it?

Did you figure this out? I'm about to take mine apart. Something I can check or look for?

Yes please. Trying to remember which hose is going to the heater and which is coming from.

The heater has an arrow on one of the hoses. Just trace back where on the engine it connects….. don’t forget this as the evaporator has the same markings.

It really doesn't matter...... it's a lot like an incandescent bulb - you need current flow. Same with the heater - if you want heat you need flow through the core. The direction of flow is pretty much irrelevant. It's just a radiator located inside the cab.

IIRC…I think it does matter. This was discussed before and the valves don’t work right if reversed or some other issue, like trapping air. I don’t remember the thread, but the debugging for heat not working was to reverse the flow. Also, the direction markings are very prominent, so they must have felt strongly about it. I might as well put it back the way it was designed.

I'll mark mine before taking it apart and post back which one runs where. Probably won't be until the weekend though.

OK @ramdough I couldn't wait until the weekend.
Here's some pics, but the gist of it is the front most hose is the inflow. If it trace that line back, it goes down along the passenger frame rail, then up towards the front of the engine near the front crank pulley. Both hoses lead here, one stops short (lower on the engine), and that's the return. The feed line feeding flow into the heater box comes from higher up.
I hope that makes sense.
