You don't need expensive tools or metal-working skills to build your own custom fuel tank for your motorized bike! If you're looking for an in-frame tank, or just something more sleek than the stock teardrop tank, fiberglass may just be the answer!
This instructables.com tutorial shows you how to make your very own fuel tank using fiberglass and fuel-safe epoxy resin! The results look very professional, IMO.
What would make this project even cooler is if you could design your fuel tank as a computerized 3D model and paste together a prototype with Pepakura, and base your tank off that!
