Technical Fuel tank

So I’m on the hunt for a fuel tank for my 26-27 model t touring. Since these tanks aren’t reproduced, I’m wondering what everyone else is running as a tank. Pics would be helpful.

Without knowing any details about your build, the first thing that comes to mind is that you will probably also be needing a fuel pump.
If you are sticking with the current configuration that I see in your pic an under ch***is tank is probably not going to fit or work with radius rods etc.
My first thought is an F1 style under seat tank that could possibly go under your rear seat, but the rear cross member maybe an issue.
I personally always like purpose built tanks that make the best use of the space and shape available and generally provide the best capacity.
In my first hot rod (Model A Tudor) I managed to get a 23 gallon purpose built tank under the floor with a parallel 4 bar rear setup.

 

I'm running a Geo Metro tank in my '27 roadster. I mounted mine behind the seat panel, under the decklid. Of course, you've got a rear seating area back there. It holds about 13 gallons and it's not a big tank dimensionally. Might want to run to the junkyard and measure one up. I bet you could make it work.

 

First is the what do I have space for where ? question. Second is how many gallon will suffice to do what you want to do. I knew a lot of guy with T's in the 70's that had ten gallon tanks and didn't get too excited as they were ready to get out of the car for a bit in that mileage range and fill it back up anyhow. Except the one with a 6 gallon tank in Texas with a thirsty engine that his road trip buddies had to carry extra gas for. About the time their gauges moved off full he was running out of gas.
You might look into a behind the seat tank out of a pickup if you can find one the right width and not too thick. Or have a tank made that fits behind the rear seat

 

For fuel tanks capacity...
if having built or building your own tank, multiply the length, times width, times depth...
take that sum and divide by 231...[cubic inches per gallon], that will give you the number of gallons in the new tank...
IMO... don't build a tank that gets a lot smaller towards the bottom, as from 1/4 tank down it will run out of gas fast...

 

I'm using an old style VW tank in my 27 roadster. They're pretty small and easy to mount.

 

These cars came with a tank under the cowl, so that's why there are no repro ones.

Corvair 63, Have you checked the Rootlieb website? They make all replacement "T" tanks including the 10 gallon oval tank that measures 9" by 28". Look on their website under "accessories". Yes it is the Rootlieb hood guy.
