Between Summit Racing, JC Whitney's and Jegs Racing catalogs you should be able to find any tank shape and size, made from either steel/aluminum racing approved, or plastic. Some are foam filled already, some are not. Some have sending units already installed, some do not. Most all have fuel pickups, and return connections, as well as vent line fittings. They even have extension necks for mounting on the side of your "car" plane.
I intend to get a dragster mini tank of about 5-6 gallons to locate behind the passenger seat, and use it on long cross countries to extend range one full hour. I will transfer fuel to the header for use, keeping the fuel system simple and mods minimal. I will not need a gauge on it since I have one on the main tank, and this one will pump into the main. A fuselage access door will be enough to get to it. Both organizations have web pages with most of the catalog items available for searching. They also have alot of the other parts that us Corvair guys are using borrowed from the rest of the small block Chevy family, like the MSD dual coil/points fixture.
