H3 Snorkel

[HummerJim]

The door seals do pretty well in deep water on the H3 (been there done that). One of the main things you need to do is raise the height of the vent tube for the automatic transmission. Transmissions don't like water in their fluid. Old Fstop told me of an ingenious way of using a marine clamp and about 3 feet of 3/8 inch hose then tie wrapping it behind the engine to the firewall. I was even thinking of running it into the cabin, but then you have to get a good seal around the hole you made for the tube and you would probably get some tranny fumes....
