1934 gasoline tank - how do it breath?
Posted by Odd Moen On 2013/5/2 14:12:36
The gasoline tank is devided in three cambers. The cambers are made by two tack welded division walls of steel. In the bottom of these division walls app 3" openings are located and covered with wire gauze to avoid dirt to be transported between the chambers by aligning the gas level.
In the top there are also openings to align the gas level.
I`m wondering about the functionality of the neck with the cap on the right side on top of the gas tank?
I put pressurized air on the tank and learned that the air didn`t come out of this neck. I suppose that the neck&cap is not allowed to breath air from inside of the gas tank to the outside, otherwise the gasoline is coming out here when the tank is filled up, as the top of the filling throat is 4" above the top of the gas tank. Is the neck&cap allowing the outside air to come into the gas tank when the air pressure on inside is lower? How will the air in the top of the gas tank be evacuated when the gas level is passing the height of the flange of the filling throat? By filling up my gas tank it take endless time to get the gas level above the connecting flange to the filling throat. As shown in the attachment, I have proposed to install a copper pipe from the top of the filling throat to the top level of the first chamber to secure to evacute the air in the top.
