On my '40 120, I discovered something I'm missing. It never dawned on me that there is a drain system for the fresh air vent on the cowl between the hood and windshield. This is to drain water incase of rain. There is hole in firewall just above the rubber grommet to have a drain empty into the engine area. So...does anyone have name for this piece and physically what is it? Just a rubber hose? Can anyone share ID dimensions.
Looking forward to hearing responses.

Not sure about 1940, but my 1937 has two drains from the cowl vent. They are just rubber hoses.

I do see in the parts list that 1940 uses one “drain tube” and 1937 uses two.

Depending on the year, there are one or two cowl vent drains. On the underside vent towards the front will be a small metal tube/hose ripple. A hose slips over that (no clamp needed) and then the hose then extends out through the firewall about an inch.

It's easier to push it in from the engine side.

Unfortunately I am not near the car right now. So I have not been able to put my hands on it to determine if a standard 1/2" ID rubber hose (like fuel line) would work. Most rubber hoses the walls are approx 1/8 thick or thicker. Does any one know if there is any restrictions around the drain nipple the hose connects to? Do I need thinner wall hose?

I'd make the hose or hoses long enough to keep water from getting on the engine.
