I haven't found anything on the web about gatt jar and aviation fuel.
How does potential water contamination get separated?

This fuel tester allows you to put preflight fuel samples back into your
airplane (a great alternative to tossing sampled fuel onto the ground: a
practice now discouraged by the EPA). Sample and check your fuel as
always. Then, as sampled fuel is returned to the tank, a unique,
built-in screen separates solids and non-petroleum contaminants, so only
clean, pure fuel is returned to the tank. Reversible sump actuator fits
both pin and petcock actuators. Wide mouth collector helps protect hands
and clothing. Resilient plastic construction makes the GATS Jar
virtually indestructible with normal handling.
