The Wisconsin-based U-Fuel organization is the oldest and largest supplier of turnkey, self-service aviation fuel systems in the world, according to Kent Misegades, U-Fuel representative. “We have thousands of fuel systems installed all over the world,” Misegades says. They built their first one (the first one) back in the late 1980s. There’s no denying that these guys have been around for a while, and maybe there’s a reason: Value. Misegades says that a “typical” two-product Avgas + Jet-A system goes for around $100,000, and that a “bare-bones” system lands at roughly $25,000.
