Aircraft fuel testers for a safer preflight
A fuel tester is the simplest piece of safety equipment in the cockpit and one of the most important. Draining a sample from each sump before flight lets you confirm there is no water or sediment contamination, that the fuel is the correct grade and color, and that nothing has settled in the tanks since the last flight. Every tester below drains cleanly into a clear tube or jar so you can inspect the sample, then return clean fuel to the tank or dispose of contaminated fuel safely.

| Innoquest Easy-Access Gulfstream Sump Tester | Innoquest | Hard-to-reach sump drains on specific aircraft |
Top fuel tester brands
Aviation Specialties (GATS Jar)
The GATS Jar is an eco-friendly, cost-effective sampler that filters water and contaminants out of the fuel so the clean AVGAS can be poured back into the tank instead of wasted. It is a favorite for pilots who want to inspect and recover fuel in one step.
ASA
The ASA dual-head fuel tester is a straightforward preflight staple that draws a clean sample for visual inspection and includes an octane chart for quick fuel-grade reference. It is a dependable pick for student and rental pilots.
Daansen
The Daansen multi-function tester detects water and dirt in the sample and adds a built-in screwdriver and sump-drain opener, combining several preflight tasks into one tool.
FuelHawk
FuelHawk precision fuel gauges give accurate, real-time fuel-quantity readings for general aviation aircraft, helping you verify how much usable fuel is actually in the tanks before you launch.
Innoquest
Innoquest builds easy-access sump testers designed for aircraft with non-standard or hard-to-reach drain configurations, so you can still draw a proper sample from every sump.
How to choose the right fuel tester
Match the tester to your aircraft and your routine. For most piston singles, a standard clear-tube tester or the GATS Jar covers every sump drain you will use. Consider these factors:
- Fuel recovery. A filtering tester like the GATS Jar lets you return clean fuel to the tank instead of discarding it, which adds up over time.
- Drain compatibility. Some aircraft have recessed or non-standard sump drains. If yours is hard to reach, a specialty tester such as the Innoquest is built for that geometry.
- Built-in tools. Testers with an integrated drain actuator or screwdriver reduce what you carry in the flight bag.
- Durability. Choose corrosion-resistant, fuel-safe materials so the tester holds up to repeated AVGAS and Jet-A exposure.
- Quantity verification. If you also want to confirm how much fuel is in the tank, add a calibrated gauge like the FuelHawk to your kit.
A fuel tester pairs naturally with the rest of your preflight gear. See our aircraft CO detectors, cockpit supplies, and the full pilot supplies and aviation equipment collection.

Frequently Asked Questions
How often should I test aircraft fuel?
You should sample fuel from every sump drain before each flight and again after every refueling, because water and sediment settle to the bottom of the tank where the drains are located and can collect at any time.
What contaminants does a fuel tester detect?
A fuel tester reveals water, dirt, rust, and sediment in the sample, and the clear tube also lets you confirm the fuel is the correct color and grade for your engine, such as blue 100LL AVGAS or clear-to-straw Jet-A.
Are aircraft fuel testers reusable?
Yes, aircraft fuel testers are fully reusable; you draw a sample, inspect it, then either return clean fuel to the tank or dispose of contaminated fuel and wipe the tester for the next use.
What is the difference between a fuel tester and a fuel gauge?
A fuel tester draws a sample from the sump drain so you can check fuel quality and contamination, while a fuel gauge such as a calibrated dipstick measures how much usable fuel is in the tank; many pilots carry both.
