Fabricating the Fuel Tank

Fuel Tank

Finished fuel tank. You might want to wear sunglasses.

The fuel tank consists of an FIA FT3 certified fuel cell bladder, custom-made for this project by Aero Tec Laboratories, inside a custom made steel/aluminum container. The bottom and back of the container are made from a single laser-cut and bent sheet of steel, while the sides, front, and top are laser-cut and bent aluminum pieces. It’s carefully designed so the interior is completely smooth with all rivets and fasteners away from the fuel cell. All the rivet holes were laser cut also, meaning there’s only one way to fit it together– the correct way. This did make it very hard to install, however, as tolerances are zero to negative.

Inspecting or replacing the fuel cell bladder should be possible by drilling out all the rivets on the diagonal front panel and removing it. Not something I want to do very often.
