I got the tank from davesmotors.com
It is their 1.5 liter single line gas tank, model jj420.
If you seal the hole in the cap of the stock tank, suction will be created in the stock tank as you use gas. That suction will pull fuel up from the aux tank.
The aux tank will enpty first. When the aux tank is empty, the stock tank will draw down.
You just have to be careful that the stock tank is air tight. Once I had a gas cap that did not seal completely, and once I had a tiny hairline crack in the stock tank. In both cases, the stock tank would not hold a vacuum, and gas was not pulled from the aux tank.
