Aviation Specialties GATS Jar Eco-Friendly Aircraft Fuel Tester with Separator

What is the GATS Jar aircraft fuel tester?

The GATS Jar is a reusable preflight fuel tester from Aviation Specialties. It is a transparent 12 ounce container with an integral fuel water separator. You sample fuel from your aircraft drains, inspect it for water and debris, and then return the clean fuel to your tanks instead of dumping it on the ground.

How does the GATS Jar let me return fuel to the tank?

The GATS Jar uses an integral fuel water separator that removes water and debris from your sample. Because the separator holds contaminants back, only clean, tested fuel returns to your tank. That lets you preserve usable aviation gasoline on every preflight check rather than discarding the entire sample on the ground.

What capacity is the GATS Jar?

How does the built-in water separator work?

The GATS Jar features an integral fuel water separator that efficiently removes water and debris from your fuel sample. Contaminants are held back inside the jar while clean fuel can be returned to your aircraft tanks. This separating action is why you can confidently put only pure, tested fuel back into your aircraft.

What fuel drains is the GATS Jar compatible with?

The GATS Jar includes a sturdy pin specifically engineered for pin-type fuel drains, making it compatible with virtually any aircraft that uses that common drain style. You press the included pin against the drain valve to release a fuel sample directly into the jar for inspection before flight.

What fuels can I test with the GATS Jar?

The GATS Jar is built for preflight inspection of aviation gasoline, letting you check any sample for water and debris before flight. The clear container and integral separator make fuel quality easy to see. As with any fuel tester, use it according to the included instructions and the procedures specified for your aircraft.

Why is the GATS Jar considered eco-friendly?

Every year over 3 million gallons of aviation gasoline are discarded during preflight fuel checks in the United States, creating environmental hazards and unnecessary cost. By returning clean, tested fuel to your tanks, the GATS Jar reduces this waste and helps protect groundwater supplies from leaded fuel contamination while saving you money on every inspection.

Does the GATS Jar save money compared with a basic fuel cup?

Yes. Traditional fuel test cups require you to dispose of the entire sample, so every preflight check throws away usable fuel. The GATS Jar lets you reuse the clean fuel by returning it to the tank, which turns a routine inspection into a cost-saving step, especially as aviation gasoline prices rise.

Who should use the GATS Jar?

It suits private pilots concerned about rising fuel costs, flight instructors teaching proper preflight procedures, and maintenance professionals managing environmental compliance. The clear construction makes fuel quality and the separating action easy to demonstrate, so it works well both for everyday personal flying and for training new pilots on sound preflight habits.

Is the GATS Jar reusable and how long does it last?

Yes, the GATS Jar is a reusable tester designed for real-world aviation operations. Pilots commonly keep one in the flight bag for routine preflight checks over the long term. Handle it normally, keep the separator clean, and avoid crushing it so it stays in good working condition use after use.
