Ryan;
The Summitracing web page search feature lists Fuel Cell tanks with a sump and pickups on the bottom as Drag or Pro Street tanks, the flat bottom tanks with pickup and vent from the top are called Circle Track tanks.
I selected the tank because it has a flat bottom and was small enough to fit with at least 1 inch to the side skin. There are other choices that 'might' fit, but still 8 gallons:

I installed a Brass 3 way valve when I upgraded the stuck fuel tank valve, The Main Tank and Auxiliary tank both go to this valve. The Boost pump and Lycoming mechanical fuel pump draw from this valve.
I got a Facet 40108 'Cube' electric fuel pump (6psi), intending to transfer fuel directly into the top of the main tank. This pump weighs just over 1 pound, so I decided to leave it out for now.
