the trick is to get the water to flow all the way to the low point

Right, but short of parking on ramps, how? And what is that part?
Holeey smokes......
I looked at the link for the hood cowl. Apparently, it doesn't currently ship to the US. How does it attach to the hood? Any idea if there are any other sources for it?Good video @dov tayles and this is exactly what I suspected (but did not have the video proof). I think the situation is worse on many vans since on that van the vent and cowl actually meet up pretty well, not so on some other vans and this is nearly impossible to align. Furthermore if you park on a flat or downward facing slope the water will not drain from the "airbox" under the hood... As an aside if you park on a flat or downward facing slope some water wont drain off of the roof where the channels end, for these reasons I park my van in my driveway (close to flat) with the front wheels on ramps.
Thus the reason I installed the hood cowl @phil mentioned. It diverts all water further down the hood instead of in the intake cowl. It seems to be holding up just fine but my van isn't getting as much use this winter as many peoples.
You might look on amazon too, it was on there at one time. If that doesn't work you could probably order it from one of the European companies that ships to the U.S. especially those in the UK.I looked at the link for the hood cowl.

Sort of @SteveSSIt seems like that hood scoop would reduce water intake while parked, but not so much while driving.
The vendor is located in Tatarastan, which is in Russia....I've been following this thread and came across this link. Van has not arrived yet, but I wonder if this would do the job. Looks pricey, but figured I would at least point it out.

Water is entering through the cabin air intake openings on the hood.Where is it getting in, I did not see it dripping down on the video? If we know the entry point, it seems like a diverter would be easy to make out of some 1/8" inch ABS sheet. A heat gun will warm it up enough to form it pretty easy. I made a couple of vortex generators out of it to mount on my bike to break up the air flow over the fairing & hitting me in the chest. The stuff is tough and fun to work with.
I replaced the little tubes with some 1/2". Drains better and doesn't clog all the time. Supported underneath with zip ties.All in all it a cheap way to some help to get rid of water sitting around. My next task is a way to seal around wiper arms, stay tune.
I didn't drill. The tube I used is a real tight fit. You can see how it is pinched in the hole.So, it is just a 1/2-inch tube? Did you have to drill out the old tube? The white color part that has a flange to keep it from going down the hole is glued in on mine, makes it hard to remove. I would maybe think about your way and still use the strainer method that seems to work for me.
