Water on passenger floor board?

Why do I have water pouring inside my Jeep when it rains? - That is a fairly common occurance. The grill on the top of your engine area (just in front of the windshield) allows fresh air into the Jeep for the heater. It also allows water and snow to collect. There is a drain-hose on the firewall about 1.75" in diameter that can get plugged. Pull off the hose, and tip it upside down. Wash it out with the garden hose in the backyard and then wash the grill-area down as well pouring as much water down as possible to wash all the trapped dirt out. Place the hose back in place and enjoy dry feet again.

I read that in the FAQ so I took a butter bowl and filled it with water and dumped it into the cowl vent, all of it came out of the bottom of the Jeep and there was no water on the floor board.

After heavy rains, there is about an inch of water on my passenger floor board. There is a little stream from the front right corner of the tub, this is just judging by the wet spots on the floor.

I was wondering where else could water be getting in? My top does not leak, and the cowl vent drains. I am rhino lined and have no carpet so it is not a huge deal, but would like to get rid of the inch water on my floor.

Also looking for the cowl vent tube, I found an elbow under my battery, it is maybe a 1/4 inch rubber hose that has nothing on the end of it and goes into the fire wall. What is this? When I dumped water into the cowl vent nothing came out of this hose.

Well I guess you have already read this by your comments.

The elbow under the battery tray is a water drain for the heater box. It is seal against the firewall from the inside.

I had not read that, I just saw the one I posted about the cowl. I will have to check the other spots.

So I think it is leaking through the body seam. Do you have to get auto body sealent or will any clear silicone caulking work? Also if it is just one spot do I need to redo the whole seam or can I just dab it on that one spot?

I'm sure you could seal it with silicone, but any auto body supply/paint store should have body sealant and I believe it's pretty cheap and you can paint over it.
