100 Series Air Filter

The idea of the hole is to let water out if any gets in. Particularly on a truck used in a water crossing with no snorkel.

I think it was one of the Jackaroo's had a one way valve on it's air filter box. Seems like a good idea.

I've often wondered where you might get something like that.

I've been given conflicting advice on what to do with that hole myself. The snorkel installation instructions said to block it off. A friend of mine who's a very good mechanic & experienced 4wder reckons leave it. His rationale - it's too small to allow much water in and if you do get any water down your snorkel through washing or a leak in the quarter panel crossing passage you really want it to get out somewhere.

Jury's still out for me. A one way self draining trap like on a compressor water filter would be good.

Unless I have misunderstood you are saying the clip off dust container is not there at all? and you are not just talking about the water drain thingo at the bottom of the bowl? From memory the 100 series bowls are a pita to clip back on compared to the 79 series. They are easy to do wrong and could have fallen off. For some reason things that fall off in the engine bay rarely dissapear so the first thing i would do is have a good look around the nooks and crannys below. Failing that it should be easy to get one from your Tojo dealer or wrecker
