The AEL mark I fuel sample kit measures what?

• A. Trace quantities of free water in gasoline or jet fuels.
• B. Measuring octane rating of fuel
• C. Testing fuel viscosity
• D. Measuring water content in diesel

Answer: (A)

Detecting trace free water in aviation fuels is essential because even small amounts can cause phase separation, ice formation in cold conditions, and fuel-system corrosion. The AEL Mark I fuel sample kit is designed to quickly indicate trace quantities of free water in gasoline or jet fuels. It uses a reagent system that reacts with water to produce a visible signal, such as a color change or a distinct separation, allowing the technician to confirm the presence of free water at trace levels. This kit specifically targets free water, which sits as a separate phase in the fuel, rather than dissolved water, which is harder to detect with this type of test. Octane rating and viscosity require different equipment and procedures, and detecting water content in diesel is a separate capability not provided by this kit.
