Model T Ford Forum: Forum 2017: What's this pipe running from my cowl tank?

So there's this brass pipe. probably 5/8" diameter, running down from my cowl tank. There's also a hole that starts up top next to the gas fill cap. What is this exactly? Drain pipe for the tank? Air breather to help with air flow? Either way it's terribly clogged, if it's a drain where's the shutoff/on?

It is there so if you spill gas while filling it will run down next to the hot motor and exhaust and not inside the car!

Over flow drain pipe.
Somebody will likely post the x-ray view of the tank showing the pipe.

One of the reasons whey this is the only Model T tank not reproduced. Pipe goes from the fill door through the inside of the tank and comes out where the sediment bowl attaches. Small screw holds the external pipe extension in place from the bowl to under the cowl where it just releases any spilt fuel on the ground. Might want to "accidentianly" spill some gas in it once in a while to keep spiders and wasps from building nests in there. Or blow some air down it once in a while.

It's been over 55 years since I owned a '26, but that drain pipe is not brass. There are two different locations for the set screw at the top, and there is a clamp half way down to secure it to the body.

You're correct. It looks more like copper or something. All I know is t's a brownish color and mostly coated in grime.

In the day they didn't have the automatic nozzles we have today and it wasn't uncommon to pour gas from a pail into a funnel or directly in to the tank, therefore spills were anticipated and common. At the best of times the tank is in an awkward location for refueling with a pail.

Very true David but if you want awkward, the Model A is even worse and if you use a funnel...:-(
