Hi all! My T is a 1924 and I am replacing the gas tank bottom with 16 gauge galvanized . from all that I have read, a vent pipe is a plus for a model t. any comments or suggestions on the best place to solder it to the tank thanks. Ken
Mine seem to work quite well with a small hole (1/16" or so) drilled in the gas cap. Not sure why you would need any additional venting. I have heard of people pressurizing the tank with exhaust gas, but I've not seen the need with a stock set up.
Hi Hal! I was thinking of plugging the gas cap vent hole and venting outside the car because of gas vapor. thanks. Ken.
You didn't mention what model so I'm guessing the tank is under the seat. ??? The tank sits pretty high so any vent will have to be above the tank. There's not a lot of room under the seat to loop tubing. If you don't loop it high and then below the cabin, you'll be dribbling gasoline that will blow back on the car and defeat your reasoning.
Perhaps using an under the seat panel will help more. Most had a cardboard panel anyway. Make an effort to seal the tank area from the cabin. The gas cap not only vents but also allows what few drops that slosh up to drain back into the tank.
The vendors sell a kit that screws into the filler opening and uses a plastic tube to vent the tank to the side opposite the exhaust. Sure does improve the ride after filling the tank! Gas cap screws into the top of the adapter
Thanks for the input guys! I am not a fan of changing something that works. since I have never owned a T before I was just thinking safety. thanks. Ken
