GATS Jar Aircraft Fuel Tester - Available in 12oz & 16oz

GATS Jar Fuel Tester – The Original, Environmentally Responsible Fuel Sampler

The GATS Jar Fuel Tester is the only fuel inspection device that allows you to safely return preflight fuel samples back into your aircraft’s tank—reducing waste and helping protect the environment by eliminating the need to discard fuel on the ground, a practice discouraged by the EPA. Equipped with a built-in filtration screen, the GATS Jar separates non-petroleum contaminants such as water and solid debris, allowing only clean, pure fuel to be returned to the tank. If jet or diesel fuels contamination of an AVGAS fueled airplane is suspected, the GATS Jar screen element can be used to help detect the presence and concentration of diesel fuel or jet fuel. Available in two sizes—12 oz and 16 oz—the GATS Jar offers the highest capacity of any AVGAS fuel tester on the market. Its wide-mouth design helps shield your hands and clothing from splashes. The reversible sump actuator is compatible with both pin and petcock-type drains, and the tester works with any petroleum fuel grade and octane, including Jet A fuel, automotive gasoline, and diesel fuel. It’s a versatile tool suitable for general aviation, automotive, agriculture, military use, and more. By enabling you to return clean fuel to the tank, the GATS Jar helps reduce fuel waste—making it not only environmentally responsible, but also cost-effective. Trap out water, filter debris down to 200 microns, and make every drop count with the trusted original fuel tester used by pilots worldwide.
