While driving through rain if you hold a paper cup horizontally out of your car window (facing forward) you will find that it collects a lot of water. So could someone explain to me what happens to the water that enters a snorkel intake under the same circumstances ? I found a string in the archives about snorkel intakes facing forward/back/sideways/revolving and I don't want to get into all that again, but in that string someone suggested that the water hits the back of the intake then runs out through the join. I would have thought that if the intake is fastened on fairly tightly only a small amount could escape that way. I also found mention of a trap in the air filter box, but that would presumably be of a finite size and would eventually fill.

Anyone know the answer?

Safari snorkels have a channel on the snout designed to direct water out the back.
I had the dust collector (donaldson) fitted once while driving on the highway in puring rain and it filled with water in one hour (and the air inlet for those is through the bottom) the system that is designed to collect dust (which it does) also collects water.

Thanks Will, I thought that there must be something to cope with the problem. Presumably other brands have similar solutions.

The trap in the filter box usually incorporates a one way valve that allows water to escape, but will not allow it to enter during river crossings & the like.

I have a Safari fitted to my LC 100 Series. Just before the new intake pipe is directed into your original air cleaner unit you should see, facing downward small duck billed shaped rubber flaps. These flaps are drawn togeather to form a water tight seal as the engine is running, however once the air pressure in the intake is at normal pressure (engine stopped) the flaps can open and allow any water to drain.
