Cowel vent and leak

I have some water in floorboards after rain. It's coming from firewall then down on trans hump then splits right and left into floorboards. Couple posts have mentioned clogged drain. How do you clean it out?

It is a big black tube about a foot long, that attaches to the firewall on the passenger side of the motor. It is held in place by a spring clip. Just remove and flush out with water and reattach. You will be good to go!

When I was rebuilding mine I noticed a short metal tube sticking out of the firewall but no hose attached to it? It's on the passenger side just above where the floor pan is attached.

i found the best way to clean the whole drain system is to pour HOT water into the cowl intake and rinse the whole thing not just the hose. about every 6mos or so i run some 30 second killer through it.

The drain hose should be higher up, than the floor pan. Like 6 (or so inches if I remember right) from the top of the hood line...

I did this with my cowl to help keep water out.

I also glued a custom cut brass screen to the underside behind the slots on this one to keep leaves out. Only problem is the snow needs to be cleaned off from it in the morning when I start the jeep in order to let the air flow through nicely.

How does the air flow into it? From the looks of the pic it's like a solid covering? Is there slots in the back towards the windshield?
