Flint Aero is a family owned business that has been engineering FAA-PMA approved auxiliary fuel tanks for Cessna airplanes since 1967. That is all we do, just aux tanks for Cessna aircraft. Our long range fuel tanks not only add fuel capacity but can also increase the gross weight of many 185, 206 and 337 models Let down for refueling and climb back up to cruise altitude make up some of the most detrimental engine time. Our tanks can contribute to significantly longer engine life by extending the range of your aircraft and reducing the need for that extra stop for fuel. Flint Aero tanks give you greater flight scheduling flexibility and provide an ever important reserve capacity for an additional margin of safety. Our kits are quite complete and come with just about everything you will need to complete the installation: hardware, fuel line, electric transfer pumps, wiring, switches, gauges, detailed installation instructions/drawings, and an STC. The tanks are carefully handcrafted from laminated fiberglass, providing maximum strength and durability while keeping weight to a minimum. After many years of service our tanks have proven extremely reliable and trouble-free. They are compatible with most leading edge STOL conversions. Our kits, in most cases, are available for immediate delivery.
